Types & Symptoms Of Dementia

---

Watching a parent change in ways that feel unfamiliar or concerning is one of the hardest challenges many adult children face. I'm going through this with my own parents so I know the angst and heartache.

I'm here to help you understand what you’re seeing, what it might mean, and how to move forward with clarity and compassion.

Understanding Dementia

Dementia isn’t a single disease — it’s a general term for a group of symptoms that affect memory, reasoning, and daily functioning. It’s caused by damage to brain cells and can progress over time. Knowing what type of dementia your loved one may be facing is the first step toward getting the right help.

Common Types of Dementia and Their Signs:

1. 

Alzheimer’s Disease

The most common form of dementia

• Short-term memory loss
• Confusion with time or place
• Trouble following conversations
• Difficulty performing familiar tasks
• Mood swings or withdrawal from social activities

2. 

Vascular Dementia

Often follows a stroke or issues with blood flow in the brain

• Sudden or step-like memory decline
• Trouble focusing, planning, or organizing
• Slowed thinking or difficulty with problem-solving
• Physical symptoms such as weakness or balance problems

3. 

Lewy Body Dementia (LBD)

Characterized by protein deposits in brain cells

• Hallucinations or visual disturbances
• Fluctuating attention or alertness
• Movement issues similar to Parkinson’s
• Sleep disturbances and REM sleep behavior disorder

4. 

Frontotemporal Dementia (FTD)

Affects personality, behavior, and language

• Personality changes or inappropriate behavior
• Difficulty with speech and language
• Poor judgment or impulsiveness
• Lack of empathy or emotional awareness

5. 

Mixed Dementia

A combination of two or more types, often Alzheimer’s and vascular

• A blend of symptoms listed above
• Can be harder to diagnose due to overlapping features
