hello dr pawate the symptoms you are describing certainly point towards a possibility of OCD but other possibilities should also be considered. It is unusual to start getting these symptoms at 60 plus age so first - were such symptoms present since a very long time but now have become worse? and does any of your first degree relatives have similar symptoms? (OCD is highly genetic) if really these have emerged recently, possibility of Degenerative disorders, seizure disorder or Space Occupying lesion should be kept. You should under go EEG and CT Scan Brain also Whatever, you should consult a good psychiatrist and start appropriate treatment as delay can reduce the level of recovery best wishes
