Hi. Very long one this, but have reached my wits end and need some support. Let's start at the beginning - my father, he was diagnosed with non-Hodgkins lymphoma, which required some substantial surgery to the back of his neck & head - removing lots of tissue and also parts of some blood vessels. Since then, my dad has progressively shown signs of losing control of his reasoning & moods. To name a few: Failure to pay the mortgage Story telling - making things up about people and places Constantly losing car keys / wallet etc Random bursts of anger Poor decision making (I.e. Being gullible/falling for sad stories) Now, there is a family history of Alzheimers on his side, but our family doctor says this is all a result of depression and bears no resemblance to Alzheimer's. Can any of you offer suggestions, or advice on where to get his behaviour assessed? My gut feeling is these are symptoms of a condition - be that Alzheimers or perhaps vascular dementia.
