[|AI|]  Hello, There are several possibilities for your fathers symptoms such as a PARKINSONISM problem as noted by his tremors in the hands and legs.  Another possibility, however, that takes into account both the nocturnal vocalizations, tremoring, and forgetfulness could be something we refer to as LEWY BODY DEMENTIA.  Usually, this entity gets much worse at nighttime or whenever lights in the patients' area/room are turned off.  He will need laboratory testing done and a visit to a neurologist in my opinion. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
