It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It would be prudent to see a doctor, preferably a neurologist. An evaluation by a psychiatrist may be also be useful. Wish you good health!

Agree with Dr Singh, see a doctor. You may well have a family history of such a disorder. Have found some anti-cholinesterase meds used in Alzheimer's may help and both SSRI's and SSNRI's have been used here. See a local psychiatrist, speech therapist, and/ or occupational therapist.
