Chronic Dizziness
Chronic dizziness is a frustrating, persistent disorder that can significantly interfere with normal daily activities and prevent people from being able to do the things they want to do. Chronic dizziness can take a few different forms, depending on what the precipitating event was, the physical and psychological contributions to the disorder, and the symptoms that are experienced.
Chronic dizziness is often initiated by a precipitating medical event. For example, an inner ear infection called labyrinthitis can cause dizziness/vertigo that lasts for several weeks, but typically resolves fully. However, some people continue to experience persistent, fluctuating labyrinthitis symptoms, including dizziness (but not vertigo) and increased sensitivity to complex visual stimuli (e.g. driving in the rain, complicated patterns), that are made worse by passive and active movements (e.g. riding in a car and walking, respectively).
To meet criteria for chronic dizziness, symptoms must be present more days than not for at least 3 months. Most people have symptoms for several hours every day. In addition, the disorder must cause significant functional impairment or distress. Triggers usually include an upright posture (standing or walking) and moving visual stimuli.
Chronic dizziness is frequently associated with an anxiety disorder that worsens symptom severity. Common symptoms of an anxiety disorder include excessive worrying about life events, loss of ability to carry out routine tasks, and anticipatory anxiety in advance of a situation that may cause dizziness. People who are anxious about becoming dizzy actually increase their risk for a dizzy spell.
Before we get into a discussion on chronic dizziness, lets briefly review dizziness types and mechanisms.
Dizziness is an umbrella term that includes the following subtypes:

Vertigo:A spinning or tilting sensation; a sense of motion when youre not moving
Presyncope:Feeling like you are going to faint (fainting is called syncope); also called lightheadedness or giddiness
Disequilibrium:A sense of imbalance or instability, often experienced when you are walking

The vestibular system is an important balance organ, and when it isnt working properly, you will feel dizzy. Consequently, dizziness is sometimes called a vestibular symptom, and disorders that cause dizziness are known as vestibular disorders.
Vestibular disorders can be caused by structural (anatomical), functional (physiological), or psychiatric (particularly anxiety) abnormalities.
Structural and functional vestibular disorders are initially acute or episodic, but they can both transition to a chronic state. Psychiatric vestibular disorders are not considered to be acute or episodic, rather, they are chronic, progressive conditions.
Chronic dizziness treatment
The most effective treatment approaches to chronic dizziness emphasize a holistic approach that addresses both physical and psychological aspects of the disorder. In many cases, people with chronic dizziness have seen several doctors in a variety of specialties without ever being accurately diagnosed, and the standard dizziness treatments they are given are often ineffective. Many people who have unsuccessfully tried medications find that physical therapy is a more effective treatment strategy.
When treating chronic dizziness, it is important to understand what caused it and what contributes to it. For example, one person may have had an acute case of vestibular neuritis that transitioned into chronic dizziness without anxiety, while someone else may have a psychiatric vestibular disorder with high anxiety and panic attacks. Treatment plans for these people may look very different. Treatments should be tailored to suit the specific needs of each patient.
Vestibular rehabilitation therapy
Vestibular rehabilitation therapy (VRT) is the gold standard in treating structural dizziness. VRT is an exercise-based physical therapy program that can alleviate symptoms associated with many forms of chronic dizziness.
VRT leads to significant improvements in vertigo symptoms, fall risk, posture and balance, and overall emotional status in people who have vestibular forms of dizziness (i.e. inner ear dysfunction). One recent study found that 79% of VRT patients reported subjective improvements in their chronic dizziness symptoms.
VRT is has also successfully helped people with mild forms of psychiatric vestibular disorders, although more serious cases may be better treated by combining VRT with behavioral therapy and, if necessary, medications.
Importantly, maximum efficacy requires a commitment from the person being treated. People who are less than 75% compliant with their physical therapy regimen have poorer outcomes than people who are fully compliant.
Cognitive behavioral therapy
Cognitive behavioral therapy (CBT) is one of the most successful behavioral therapies for helping people manage chronic dizziness that has a significant psychological component. CBT identifies negative thought patterns and replaces them with positive ones. Over time, this can significantly reduce chronic dizziness symptoms and improve mood and outlook.
Chronic dizziness that has a structural origin (e.g. peripheral vestibular system disorder) or a functional origin (e.g. vestibular neuritis) may respond well to CBT, but physical therapy should also be used to address the physical aspects of the disorder.
Depending on the cause of your chronic dizziness, some medications may help you manage the symptoms:

Selective serotonin reuptake inhibitors (SSRIs) are antidepressants that can be very helpful for people who have psychiatric vestibular disorders or anxiety with dizziness.
Benzodiazepines are prescription anti-anxiety drugs that can reduce dizziness and anxiety, but they are for short term, intermittent use only, as they are associated with a high risk for developing physical and psychological dependence/addiction.
If your chronic dizziness is related to vestibular migraine, anti-migraine drugs may reduce symptom severity and duration.
Nausea and vomiting can be treated with prescription antihistamines or anticholinergics.

Although medications have their place in treating anxiety and dizziness disorders, in many cases physical therapy and behavioral therapy are as (or more) effective than pharmacological treatment options.
Central nervous system therapies
Until recently, it was thought that chronic dizziness was the result of impaired compensation after an injury. Compensation is the process of recovering normal function through central and peripheral nervous system reorganization; in other words, your nervous system adapts to overcome damages associated with the injury. Recent evidence suggests that the recovery process is even more complex and includes changes in the way the brain integrates and processes spatial information. If this is proven to be true, it suggests that a peripheral nervous system disorder can have long-term functional consequences in the central nervous system.
Treatment options that target the central nervous system are currently being tested, with some promising preliminary results. Transcranial cerebellar direct current stimulation (tcDCS) was shown to enhance the benefits that physical therapy provides, and repetitive transcranial magnetic stimulation (rTMS) treatment was shown to reduce the frequency and severity of dizziness spells.
Chronic dizziness and lightheadedness
Lightheadedness, also known as presyncope, is the feeling that you are about to pass out. Chronic dizziness and lightheadedness may be experienced together, especially if a dysautonomia (a disorder of the autonomic nervous system) or a dysrhythmia (abnormal heartbeat) is also present. Lightheadedness can also be caused by orthostatic hypotension (low blood pressure) that occurs when you stand up too quickly.
Chronic dizziness and headaches
Vestibular migraine is a chronic headache disorder that often includes dizziness or vertigo. Vestibular migraine is characterized by light sensitivity, imbalance, nausea/vomiting, ringing in one or both ears, spatial disorientation, and intolerance to moving visual stimuli.
Chronic subjective dizziness
Chronic subjective dizziness (CSD) is a unique type of chronic dizziness. It is a progressive disorder that is characterized by disequilibrium and hypersensitivity to complex visual stimuli. CSD is not caused by vestibular dysfunction, and dizziness is linear, rather than vertiginous. Unlike some types of dizziness that are obvious to observers, the dizziness associated with CSD is called subjective imbalance because even though the person with CSD feels imbalanced, they would not appear dizzy or off-balance to an observer.
Why some people develop CSD is not yet clear. Evidence suggests that both physical and psychological factors contribute to CSD, and many CSD symptoms are emotional or behavioral. CSD was originally thought to be a psychogenic disorder; that is, a disorder of the mind, without any physical contribution. We now know that there are psychological and physical components to CSD, but the majority of people ('60%) with CSD also have an anxiety disorder.
There are three types of CSD:

Otogenic CSD:Dizziness developed as a result of a temporary medical condition (e.g. vestibular neuritis) and there was no history of anxiety before the inciting event
Psychogenic CSD:Dizziness develops in the absence of an apparent physical cause and coincides with the course of an anxiety disorder
Interactive CSD:Dizziness developed after a transient medical condition in someone with a predisposition to, or a history of, anxiety disorders

In order to be diagnosed with CSD, the following diagnostic criteria must be met:

Persistent dizziness without vertigo
Hypersensitivity to ones own movement and the movement of objects in the environment
Symptoms of CSD are exacerbated by complex visual stimuli (e.g. driving in the rain, moving through a crowd)
Symptoms must be present for at least 3 months
No evidence of a vestibular disorder or another physical cause (e.g. brain lesion)
Balance function test results do not identify the patient as having impaired balance

Treatment options for CSD are similar to those for other types of chronic dizziness, including VRT and physical therapy, cognitive behavioral therapy, and medications.
Chronic dizziness and fatigue
Fatigue is a key trigger of dizziness. Usually, fatigue and dizziness are transient symptoms that resolve with rest, but there are some chronic conditions that include fatigue and dizziness.
Chronic fatigue syndrome
Chronic fatigue syndrome (CFS) is a condition that is characterized by overwhelming fatigue, even after a good nights sleep. In addition to dizziness, CFS symptoms include muscle pain, headaches, difficulty thinking or focusing, insomnia, rapid heart rate, and flu-like symptoms. The cause of CFS is unknown, but stress and anxiety may have a significant role in the development and persistence of CFS symptoms.
Postconcussional syndrome
Fatigue and chronic dizziness are common symptoms after head trauma or whiplash. Other common symptoms include irritability, mood swings, dysphoria, insomnia, weakness, headache, short term memory loss, and inability to focus. Postconcussional symptoms often resolve within a week or so, but they may persist for several weeks, depending on the severity of the trauma and the care received after the accident.
Other causes of dizziness and fatigue

Low blood pressure and low blood sugar are two common causes of dizziness and fatigue, but they are usually temporary conditions. However, unmanaged diabetes, malnutrition, anemia, and obstructive breathing disorders (e.g. sleep apnea, emphysema) can cause persistent dizziness and fatigue.
Vestibular migraine may also cause episodic fatigue and dizziness. Migraine frequency can vary from several attacks per year to near-daily attacks, and dizziness and fatigue may coincide with the migraine or may occur before or after the migraine.
Somatic symptom disorder (SSD) is a poorly understood condition that is characterized by persistent physical symptoms (including dizziness and/or fatigue) that do not have an obvious medical explanation. People with SSD are preoccupied with their symptoms and find them to be very disruptive or distressing.

Dizziness and nausea
Dizziness and nausea are non-specific symptoms, meaning that there are multiple potential causes. Chronic dizziness is often associated with increased sensitivity to complex or moving visual stimuli, which can cause nausea and motion sickness, even if youre not moving. If you regularly suffer from dizziness and nausea, you may want to make an appointment with your doctor to learn about your options. There are several medications that may reduce the severity of your symptoms.
Importantly, dizziness or vertigo that is accompanied by ongoing vomiting could indicate a serious, even life-threatening medical issue, and you should seek medical treatment immediately.

Ken Faces Two Fears with a Flight to the Ocean

We all have fears in our lives, and at certain times, most of us would admit that theyve held us back from doing something we wanted.But, when it comes to fear, theres also a silver lining: the feeling of overcoming it and moving forward. And from that day forward, that personal victorythat sense of accomplishment is something we can turn to whenever we need some extra courage.Ken, age 70, is no stranger to adversity and fear. And in this season of his life, hes been reflecting on his fears and is no longer content letting them hold him back.One fear has been with him since he was young. Kens family lived close to an airport while he was growing up. Standing in his backyard, he would look up and marvel at the airplanes coming and going all day long. He wondered what it would be like to be inside one of these planes, looking out the window and floating through the clouds. But paired with his curiosity, a sense of fear was also growing inside him.This fear of heights and flying has followed Ken into adulthood. Adulthood came early for Ken, as hes been working hard to provide for himself and his family for as long as he can remember. In fact, Ken was already working at age 12.Ken had a job in a state park close to his home. One day, while Ken was helping remove debris in the park, a falling tree knocked him into the water. Ken was stuck, and he remained submerged until he was rescued.It was a terrifying moment that has stayed with him since that day, resulting in a deep fear of water.Its true that Ken has faced many obstacles and heartbreak throughout his life. But hes never allowed that to stop him from working hard, especially when it comes to providing for others. Ken is proud to have raised a family, including adopting two children with his wife, Elizabeth. He shared that this has made him the proudest and happiest hes ever been.Those who know Ken well would tell you hes the kind of person who shows he cares through his actions. Like how he mowed his mothers lawn for over a decade, caring for her until she passed away three years ago.Ken was everyones favorite BINGO caller at his local church and would help them with maintenance and by fixing things whenever he could. The same goes for any neighbor or friendall they had to do was ask, and Ken would be there.Kens dedication and generosity have kept him continually working, and not having many opportunities to do something meaningful for himself. But, recently, Ken has expressed the urge to conquer his fears.When Wish of a Lifetime heard Kens story, we were honored at the chance to help him take some time for himselfand to face his fears in the process by flying on a commercial flight for the first time.When asked what this experience would mean to him, Ken said, Id be happyId get to do something I never did and face my fear of going high.But thats not the only fear Ken would face during his wish of a lifetime!Every flight must have a destination, and Kens was the ocean. Ken was thrilled to share this special trip with his wife Elizabeth. Together, they flew from Pennsylvania all the way to Florida, landing in Tampa.Kens first time on an airplane was positive, and he said the flight felt like riding in a Cadillacit was so smooth.After they arrived at sunny Clearwater Beach, they could see the glittering, white sand welcoming them. Hand in hand, Ken and Elizabeth walked across the beach, taking in all the sights and smells of the ocean.I think he was amazed, Elizabeth said, describing the moment when Ken saw the ocean for the first time in his life. With deep emotion breaking up her voice, she expressed how much the experience meant to them both.Thank you guys very much, I dont know how to express the thank you, I really enjoyed it, she said.As he stood with the tide tickling his feet, Ken felt the warmth of the sunshine on his back, but also the glow of pride from within him.I feel this would make me fulfilled that I overcame two lifelong fears, he said.Reflecting on his wish, Ken said he hoped his story could help others to do the same, at any age. And, to keep hope alive, even through challenging times:Keep your nose to the grindstone, he said. Someday, something good will happen.

The Impact of FTRI Specialized Phones: Enhancing Communication for Floridians

Since 1991, Florida Telecommunications Relay, Inc. (FTRI) has improved the lives of Floridians experiencing hearing loss and speech impairments, through its specialized telecommunications Equipment Distribution Program (EDP). Established by Floridas Telecommunications Access Systems Act (TASA) in response to the passage of the Americans with Disabilities Act of 1990, FTRIs EDP oers an array of devices designed to bridge communication gaps.  Per TASA, a monthly 7-cent surcharge on landline phone bills covers the cost of FTRI distributed equipment, and the Florida Relay Service.  By providing equipment at no cost to consumers, FTRI is empowering individuals to lead more independent lives while remaining connected to the world. Let's take a look at several FTRI specialized devices and explore some heartwarming client stories that illustrate their profound impact on everyday lives.   Understanding FTRI Specialized Phones   FTRI specialized equipment caters to a range of communication needs. The devices include amplified phones, cell phone amplifiers, captioned telephones, text telephones (TTYs), and alerting devices. Each type is engineered to address specific needs:   1.     Amplified Phones: These phones are equipped with volume controls that can amplify sound significantly, up to 50 decibels, making it easier for individuals with hearing loss to understand conversations. They also feature tone settings, loud speakerphones, back-lit buttons, and loud ringers.2.     Cell Phone Amplifiers: Amplifiers use Bluetooth technology to wirelessly   pair with smart phones (Android, iPhone).  These portable, rechargeable devices allow a user to enjoy many of the same features found on standard amplified phones, such as volume and tone controls, hearing aid compatibility, and loud speakerphones.   3.     Captioned Telephones:  These devices display real-time captions of the conversation on a large screen, helping those with severe hearing loss to  read what the other party is saying.  Screens can be customized to a users preference, and call transcripts can be saved for future review.   4.     Text Telephones (TTYs): TTYs allow individuals with hearing or speech impairments to communicate via typed messages.   5.     Alerting Devices: These include flashing lights and loud ringers to alert individuals to incoming calls.   Transformative Client Stories   Jack and His Amplified Phone   Jack, a 75-year-old retired teacher, began experiencing hearing loss a few years ago. As his hearing deteriorated, he found it increasingly difficult to keep up with phone conversations, particularly with his grandchildren who live out of state. The frustration of missing out on these precious interactions led him to seek help from FTRI.   Upon receiving the Clarity XLC8, John noticed an immediate improvement. The adjustable volume and tone controls allowed him to customize each call. For the first time in years, he could clearly hear his grandchildren's voices. The device not only restored his ability to communicate, but also brought immense joy back into his life, through an improved connection with his loved ones.   Dave and his Cell Phone Amplifier   Like so many other Floridians, Dave disconnected his landline years ago.  He relied on his iPhone to make all his phone calls. Over time, however, he found himself using texting to avoid making calls whenever possible, because the iPhones volume was simply not loud enough for him to hear conversations clearly.   Daves daughter reached out to FTRI with questions about the Clarity XLCgo Cell Phone Amplifier, hoping it might be easy enough for her father to operate.  Both father and daughter were delighted to learn that the XLCgo connects to smart phones by Bluetooth quite easily, and is designed to be used both at home and on the go.  Once Dave had paired his iPhone to the XLCgo and realized he could once again enjoy conversations over the phone, there was no looking back for him.   Maria and Her Captioned Telephone   Maria, a 62-year-old librarian, was diagnosed with profound hearing loss, which made phone conversations nearly impossible.  This posed a significant challenge in her life, where communicating over the phone was essential for both personal and professional reasons.  Feeling isolated and frustrated, Maria turned to FTRI for a solution.   FTRI provided Maria with a captioned telephone.  This device transformed her ability to communicate. The real-time captions allowed her to read conversations, ensuring she could understand every word spoken.  Saving call transcripts for future reference became routine for her, especially for calls with her doctor to discuss medications. The captioned phone improved her life by restoring her sense of independence, safety, and competence.   Sam and His TTY Device   Sam, a 45-year-old software developer, was born with a severe speech impairment. Communicating over the phone was always a daunting task for him, often requiring the assistance of a family member or colleague. This dependency made Sam feel self-conscious and restricted his ability to handle personal and professional matters independently.   FTRI introduced Sam to a TTY device and the Florida Relay Service, which revolutionized his communication experience.  The TTY allowed Sam to type his messages, which were then converted into voice for the person on the other end of the line by the Relay Service.  Likewise, he received typed responses that he could read. This device gave Sam the autonomy he craved, enabling him to manage personal communications without assistance. The TTY device empowered   Sam, boosting his confidence and fostering a greater sense of independence. The Broader Impact of FTRIThe stories of Jack, Dave, Maria, and Sam are just a few examples of how FTRI specialized phones are transforming lives across Florida. By providing these devices at no cost, FTRI is removing financial barriers that might otherwise prevent individuals from accessing essential communication tools. This initiative is fostering inclusivity, ensuring that everyone, regardless of their impairments, can stay connected with the world around them. Moreover, FTRI's eorts extend beyond just providing devices. The organization also oers training and support to help users get the most out of their specialized phones. This comprehensive approach ensures that individuals are not only equipped with the necessary tools but are also confident in using them eectively. To learn more about FTRIs Equipment Distribution Program, visit, or call 800-222-3448.

How Walking Can Boost Your Brain Power

Your brain isnt exempt from the aging process. In fact, cognitive decline technically begins as early as your thirties. But that doesnt mean you should just give in and allow time to take its toll without a fight. You can slow and, in some ways, even regain some of your cognitive health. And the simple act of regular walking can play a key role in boosting your brain power.When you hit your 30s, your working memory begins to fade so that recalling bits of information and passwords becomes more of a challenge. By the time you slide into your 40s, you begin to lose brain volume at the rate of 5% per decade. And of course, this affects memory, recall, and focus.But a recent study suggests that you can reverse the deteriorating effects of aging on your brain. The study revealed that six months of regular, brisk walking improved more than just cardiovascular fitness. It also brought improvements to the brains white matter and memory. What does this mean for you? And how does walking impact dementia and overall age-related memory loss? Heres what we know.Walking Improves White Matter and MemoryThe study compared walking to other forms of exercise such as stretching, balancing, and choreographed dancing. The participants were healthy but inactive adults, over half being female. All were over the age of 60. They had no history of dementia, stroke, or other neurological issues.Researchers established their baseline measures in areas of cardiorespiratory fitness, memory, and processing skills. They also performed an MRI to capture the function and health of existing white matter. The participants engaged in exercise three times per week for six months. The walking group took a brisk 40-minute walk each session.At the end of the study, researchers repeated the brain tests for comparison.Walking Boosts Brain Power More Than DancingWalkers and dancers had better cardiovascular health after the six months of routine exercise. And researchers also found that both groups experienced improvements in white matter. But the positive changes in the white matter of the walking group were more prevalent. According to the MRIs, certain parts of the brain were larger and lesions (indicating damage to the brain) had shrunk during the study.Researchers targeted specific regions of the brain for measurement, regions that are more susceptible to decline during aging. The research is crucial to scientists, proving that white matter is responsive to change and is essentially pliable. Deterioration at this stage isnt necessarily fixed.Walking Is Good for Your Heart and BrainOnly the walking group experienced changes in white matter that were associated with improved memory. But researchers arent sure why walking had a greater impact on white matter and memory than dancing. Similar results were expected since both activities are moderate intensity cardiovascular exercises. Its possible that the instruction the dancers received kept them from more vigorous and constant movement. This means that the key to boosting memory power is aerobic exercise, constant movement with a steady supply of oxygen.Exercise that consistently elevates your heart rate is good for your heart, and research continues to reveal that what is good for your heart is good for your brain too. Aerobic exercise increases oxygen to all parts of your bodyincluding your brain. This increased oxygen can lower high blood pressure, one of the biggest risk factors for neurological diseases and dementia. And that risk is further diminished since routine physical activity also decreases stress and improves sleep, both of which impact memory.The study is also valuable since its one of the few of its kind that was conducted as a controlled trial. Previously, most studies asked participants to report activities they were already doing rather than coming to exercise in a controlled environment.What About Gray Matter?Most of the previous studies on physical activity and cognitive decline focused on gray matter, your brains outer layer where many of your neurons are concentrated. But this research zeroed in on the lesser studies aspect of your brainwhite matter. Its found in your brain's deeper tissues. White matter includes extensions of neurons called nerve fibers. While your gray matter can be likened to a light bulb and your white matter to the electrical wiring that carries the current.Yes, gray matter is important, but to battle cognitive decline and age-related memory loss, you also need to revitalize and support the white matter that keeps everything going. We now understand why walking is powerful for your brain as it impacts both white and gray matter.Time to Start Walking for Brain HealthWhite matter is prone to degeneration whether due to healthy aging or dementia. If you want to keep your mental acuity for as long as possible, consider adding some brisk walking to your schedule at least three days per week. If youre new to exercise or walking, its okay to start small work your way up to 30-40-minute sessions. This will give you maximum impact, especially if youre only walking a few times per week.But walking benefits your health far beyond boosting brain power.
