Tampa · Statewide Florida Telehealth
A brain health and brain longevity physician in Tampa, for patients across Florida.
Brain fog, memory change, unreliable sleep, and a family history of dementia are not separate problems. They are the visible output of sleep, vascular and metabolic health, hormones, nutrient status, mood, hearing, and any prior head injury. Dr. Marissa McCarthy measures those drivers together, then builds one plan with named targets, by secure video.
Measured, not guessed at
Brain health is a physiological state, which means it moves when the inputs move, and it can be documented. A baseline here combines a deep history, validated cognitive screening, sleep assessment, and metabolic, vascular, inflammatory, nutritional, thyroid, and hormonal laboratory measures. Those become the reference point against which every later change is judged.
Dr. McCarthy is board certified in Physical Medicine and Rehabilitation with subspecialty certification in Brain Injury Medicine, which means the plan accounts for how a brain recovers, not only how it performs.
Reasons patients come to us
Brain fog and slower thinking
Word-finding trouble, mental fatigue in the afternoon, needing to re-read, or losing the sharpness you used to rely on.
Memory concerns
Your own concern or a family member's, evaluated with validated screening rather than reassurance, including mild cognitive impairment questions.
Family history of Alzheimer's disease
A personal risk profile built while the modifiable drivers are still modifiable, with a plan and re-measurement.
Poor or non-restorative sleep
Insomnia, sleep apnea risk, shift-work disruption, and the glymphatic clearance that deep sleep provides.
Cognitive performance and longevity
Executives, professionals, and athletes seeking measured optimization of attention, processing speed, and recovery.
History of concussion or head injury
Prior injury changes recovery capacity and belongs in every long-term brain health plan, whether it happened last year or decades ago.
How the work is structured
Baseline
Extended history, validated cognitive and sleep measures, medication and supplement review, prior head injury documentation, and comprehensive laboratory testing when clinically appropriate.
Interpretation
Findings read together rather than in isolation, with the two or three highest-yield domains identified for this specific person.
A written plan
Sleep, vascular and metabolic correction, movement, nutrition and nutrient repletion, hormone evaluation where indicated, hearing, and cognitive load management, each with a target.
Re-measurement over time
Repeat measures, adjustment, direct physician messaging, and a rapid pathway if a new head injury or acute cognitive change occurs.
Laboratory testing, imaging, medications, pharmacy dispensing, supplements, wearable devices, and outside vestibular, vision, or physical therapy services are billed separately from membership and consultation fees.
Serving patients throughout Florida
The practice is based in Tampa and cares for patients across the state by telemedicine, including Tampa, St. Petersburg, Clearwater, Brandon, Wesley Chapel, Lakeland, Sarasota, Naples, Orlando, Jacksonville, Miami, West Palm Beach, and every community in between. There is no in-person clinic; all visits are conducted by secure video.
Questions patients ask before booking
What does a brain health doctor in Tampa actually do?
A brain health physician evaluates the systems that determine how the brain performs: sleep quality and sleep apnea risk, blood pressure and vascular health, insulin resistance and metabolic markers, thyroid and hormone status, nutrient status, hearing, mood, medications, and any history of head injury. Those findings become one written plan with named targets and repeat measures rather than a list of general advice.
Is there a brain longevity doctor in Florida who works by telehealth?
Yes. Raeven Health is a concierge telemedicine practice based in Tampa and serving patients statewide. History, validated cognitive screening, sleep review, laboratory interpretation, program design, and longitudinal follow-up are all delivered by secure video. Laboratory draws, imaging, and in-person therapy are coordinated locally when indicated.
I have brain fog and my labs were called normal. What now?
Normal is a wide range, and most standard panels never test the drivers that matter most for cognition. A brain health evaluation looks specifically for sleep-disordered breathing, chronic short sleep, thyroid and sex hormone change, iron and B12 status, insulin resistance, inflammatory load, medication effects, mood, and unresolved concussion, then treats what is found.
Can dementia or Alzheimer's disease be prevented?
No physician can guarantee prevention, and we do not claim to. Large studies show a meaningful share of dementia risk is associated with modifiable factors, including hearing loss, hypertension, physical inactivity, diabetes, smoking, excess alcohol, depression, social isolation, obesity, and traumatic brain injury. Addressing those earlier is the most credible risk-reduction strategy available.
At what age should I start?
Most dementia risk is established in the fifteen to twenty years before symptoms appear, which makes the thirties, forties, and fifties the highest-leverage window. That said, evaluation is worthwhile at any age, including after symptoms have started, because the modifiable drivers stay modifiable.
Do you work with executives and high performers?
Yes. Cognitively demanding work exposes small deficits in sleep, stress physiology, metabolic health, and recovery long before they would show up as a diagnosis. Executives, physicians, attorneys, founders, and athletes commonly enroll for measurable cognitive performance rather than for a complaint.
How is brain health measured?
Through a detailed history, validated cognitive screening, sleep assessment, and metabolic, inflammatory, nutritional, thyroid, and hormonal laboratory testing. Those measures create a documented baseline so change over time can be observed instead of guessed at.
