from the complaints it appears a case of bradykinesia, a generalised slwoness of movements. A detailed history and proper examination is however warranted for any confirmed diagnosis. I would need to know if he Is also having resting tremors in hands, dufficulty in walking, is his gait is robotic,etc if yes it points towards a Parkinson s disease. Is he on any medications like antipsychotic or even anti depressant, to rule out any drug induced cause. Has he had an head injury in past? Is he on anti hypertensive meds? these are some imp points needs to be clarified, before any certain diagnosis is made. I suggest get an MRI brain done, consult a neurologist. let me know the results. thanks, welcome for further consultation. stay healthy Dr Pankaj Borade
