Posterior Cortical Atrophy (PCA) is a form of Alzheimer's that mainly affects the back part of the brain, which handles visual and spatial processing. Unlike typical Alzheimer's, memory problems often come later — the first signs are usually vision-related, even though the eyes themselves are healthy.
Common symptoms include:
- Trouble reading or losing your place on a page
- Difficulty judging distances or bumping into things
- Getting lost in familiar places
- Struggling with tasks like writing or using tools
- Seeing things that aren't there
- Mood or personality changes There's no cure for PCA, but medications used for Alzheimer's — like donepezil, rivastigmine, or memantine — may help slow symptoms and support daily function. Always speak with a doctor about what's right for your loved one.
Supportive care makes a big difference too. Some helpful strategies include:
- Adding extra lighting and high-contrast colors on stairs or doors
- Using large-print books or mobility aids
- Occupational or speech therapy to help with daily tasks
- Keeping a calm, consistent daily routine
- Offering reassurance and gentle comfort during moments of confusion Caring for a loved one with PCA can be emotionally and physically demanding. A myALZteam member shared that massaging their loved one's hands with a calming lotion while speaking softly helped ease distress.
Don't forget to care for yourself too. Small things like short walks, staying hydrated, and sticking to a sleep routine can help you stay strong for your loved one. You can't pour from an empty cup! 💛
