There are lots of brain diseases so the symptoms for all of them are very different!

In general, something in your brain will be altered. We can group diseases into common themes, for example diseases that feature accumulations of sticky proteins in your brain are called proteinopathies. These include Alzheimer’s disease, Parkinson’s disease, and frontotemporal dementia. In other diseases, certain cell types are affected in your brain. For example, in multiple sclerosis, the support cells that wrap around your nerve cells are damaged, causing them to be faulty in transmitting electrical signals to each other.

The clinical symptoms for every disease is different. Some diseases will give you motor symptoms, like Parkinson’s. The patient experiences shakiness and sometimes they can’t control their arms and legs moving. In other diseases, like Alzheimer’s, the patient experiences memory loss and confusion.
