Hello Mr. Martin
Welcome to Health Care Magic
The symptomatology you have described are trouble in speech, and forgetting things etc. This may be due to two reasons-
One thing is post trauma sequel. After
head trauma to head patients may develop forgetfulness, memory impairment, irritability, mood swings etc. But to confirm this you have to get MR scan of your wife done to find any significant lesion if any.
Other possibility is
Dementia due to age, or Alzheimer's disease. As Alzheimer's disease may present with symptoms like forgetfulness, change in behavior, irritability and other cognitive dysfunctions. As she is 61 and also she is having the history of trauma to head, most likely her symptomatology is due to Alzheimer's dementia. I will advise you to take her to a good
Psychiatrist and get her evaluation done. Tests like Mini
Mental Status Examination can be applied to her to check for cognitive decline.
Although dementia is irreversible but we can stop the progression of disease. Medicines like Memantin,
Donepezil are very effective in dementia.
Hope I cleared your doubt.
Thanks
Dr. Seikhoo Bishnoi
