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 DizzinessÂ
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 TogetherÂ
“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.
