Can anyone help me getting the links for different social communities (available worldwide) of patients from neurodegenerative and psychiatric disorders like Alzheimer's disease, Parkinsons' disease, Huntington's disease, ALS, MS, Ataxia, Mood disorders, depression, PTSD, and also brain-related orphan diseases like dravett syndrome, Ataxia telangiectasia, Batten Disease, etc.

It will be a great help if anyone can share this information with me.
