BRAIN HEALTH AND ALZHEIMER’S

Alzheimer’s disease devastates brain health by causing neurons to die, leading to dramatic shrinkage (atrophy) and disruption of communication, primarily due to toxic beta-amyloid plaques and tau tangles, affecting memory, thinking, and daily function, though adopting a healthy lifestyle with physical activity, proper diet (like Mediterranean), mental challenges, good sleep, and managing conditions like high blood pressure can significantly support overall brain resilience and potentially lower risk.

How Alzheimer’s Affects the Brain

Protein Buildup: Abnormal clumps of amyloid plaques and tau tangles form, disrupting nerve cell (neuron) communication.

Neuron Loss & Shrinkage: Neurons stop working, lose connections, and die, causing brain regions (especially memory centers like the hippocampus) to shrink (atrophy).

Inflammation: Microglia (immune cells) become inflamed and fail to clear debris, contributing to neuron damage.

Energy & Blood Flow Issues: The brain may lack glucose for energy, and blood supply can become insufficient.

Signs of Brain Decline 

Memory loss (early stages)

Difficulty with language, reasoning, and problem-solving

Impaired decision-making

Changes in social behavior, mood, or personality

Inability to care for oneself (advanced stages)

Boosting Brain Health (Prevention & Management) 

Physical Activity: Regular exercise (like fast walking, cycling) is crucial.

Healthy Diet: Focus on the Mediterranean diet (plant-based, olive oil, fish).

Mental Engagement: Learn new things, play games, and challenge your brain.

Good Sleep: Aim for at least 7 hours nightly.

Hydration. Stay hydrated: Drink 6+ glasses of water daily.

Manage Health Conditions: Control blood pressure, diabetes, and maintain a healthy weight.

Social Connection: Stay socially active.

Protect Your Head: Wear helmets and seatbelts.
