Conversation: The conversation between human and AI assistant.
[|Human|] The husband of a client who suffered subdural hematoma at age 16 through football accident, now 60 years old, has been exhibiting impulsive spending,impulsive socializing, anger behaviors, which have increased over last 10 years, culminating in spending and anger behaviors worrisome to his wife.  He was diagnosed with PTSD around,95 and now receives disability payments.  It seems to me the PTSD may have been a misdiagnosis conjured by attorney who helped him with disability re-application.  My question is: would his original hematoma be implicated in his current behavioral problems?
[|AI|]  The current scenario depicted by you appears to be a part of mood disorder (likely to be Bipolar Disorder late onset type) where mood fluctuations do occur between depression and mania. Hematoma sustained at age of 16 is unlikely to implicate current symptoms directly however there could be a possibility that he also had some neuronal damage like concussion or minor intracerebral bleed which can manifest later. Sometimes Personality changes are seen in cases with head injury which develop within a year or two of the damage. Here in your description it is not clear whether these behavioral problems started gradually after injury or has been noticed only off late? Nevertheless it would be advisable to get him evaluated with a neuropsychiatric, get an imaging (MRI brain preferably) if not done in recent times as well as monitor for any memory & other cognitive deficits. This could help not only in identifying the cause but also in planning intervention if required.
