I'm worried about dementia, 29 will cbt help?

Dementia and CBT: Can you give more information about the worry you have about dementia, and what 29 in your question means? The onset of dementia is 65 or older (with 5% in the 40's and 50's for alzheimer's). Cbt could possibly help with anxiety, although it depends upon the individual--that would require an evaluation. You might want to consider counseling now for your worry, and to deal with your anxiety now.
