• most common in older adults
👉 Dementia is not a normal part of aging—but risk increases with age.
2️⃣ How it happens
Dementia occurs due to damage to brain cells.
• brain cells lose function or die
• connections between brain areas weaken
• information processing becomes impaired
👉 Different causes affect different parts of the brain.
3️⃣ Common types of dementia
• Alzheimer’s disease
- most common type
- gradual memory loss and confusion
• Vascular dementia
- related to reduced blood flow in the brain
- may occur after strokes
• Lewy body dementia
- can cause confusion, hallucinations, and movement problems
- symptoms may fluctuate
• Frontotemporal dementia
- affects behavior, personality, or language early
- memory may be less affected at first
👉 Different types may have different patterns and progression, but all can affect daily functioning over time.
4️⃣ Common causes

• need for increased support and care
8️⃣ Management / treatment
• medications to slow progression (in some types)

• support for daily living and caregivers
9️⃣ Diagnosis
• medical history and cognitive testing
• blood tests to rule out other causes
• brain imaging (CT or MRI)
👉 Early diagnosis helps plan care and support.
