BRAIN HEALTH AND INCREASED DIZZINESS

Increased dizziness, particularly when linked to vestibular dysfunction, is now recognized as a potential early indicator of cognitive decline and a prediagnostic symptom of dementia. It is strongly associated with deficits in executive function, memory, and visuospatial abilities, often characterized as mental fogginess.

Key Connections Between Cognitive Health and Dizziness 

Cognitive Decline Link: Studies indicate that older adults with chronic dizziness or vertigo are more likely to exhibit signs of cognitive impairment.

Vestibular System & Brain: The balance system (vestibular system) shares neural pathways with cognitive functions. When the brain must overcompensate for a dysfunctional balance system, it often comes at the expense of memory, attention, and executive tasks.

Specific Deficits: Long-term dizziness is associated with declines in visuospatial skills, memory, and processing speed.

Neurodegeneration & Balance: Patients with neurodegenerative diseases (like Alzheimer’s or Parkinson’s) often experience increased dizziness due to poorer postural control.

Common Causes: Beyond cognitive issues, dizziness can stem from cardiovascular issues, medication side effects, and sensorimotor impairments.

Symptoms Often Reported Together 

“Brain fog” or mental fatigue.

Difficulty concentrating or multitasking.

Memory loss.

Disorientation.

Managing The Problem

If you are experiencing new, frequent, or worsening dizziness, it is important to consult a healthcare professional for a thorough evaluation of both your vestibular and cognitive health. 

Advice For Caregivers

Identify Triggers: Document when dizziness occurs—common triggers include rising too fast, dehydration, missed meals, or overheating.

Safety Improvements: Install grab bars in bathrooms, use non-slip mats, remove throw rugs, and improve lighting to prevent falls.

Hydration and Nutrition: Ensure the person drinks fluids regularly, as dehydration is a major cause of dizziness.

Medication Review: Have a pharmacist or doctor review all medications, specifically blood pressure drugs or antidepressants, which can cause dizziness.

Slow Movements: Encourage the person to move slowly when changing positions, such as moving from lying down to sitting, or sitting to standing.
