I am new to this information exchange and have been following with great interest the postings since I joined a week ago. My father now 76 years old was diagnosed with PD 3 years ago. I watched him slowly change from a very active and interactive man to a quite depressed and more and more physically impaired man.I thought it was a depression since my parents had relocated across the country to be near their children and grandchildren. Dad knew something was happening but couln't turn it around( read with interest the postings on depression). At the time of his diagnosis , he felt relieved- now he could deal with this. Little did we know. Dad was quite stable for a year- however became aware of memory loss and an increasing anxiety around common activities. He had a medication change last June- from sinemet 100/25 3 x a day to sinemet sr 200/25( I believe) 2x a day and everything changed. Dad started finding it very difficult to be around too many people- an increase in memory changes then hallucinations ( 8 people in his living room- quietly sitting with him) became part of his world. He could point them out to me and said very lucidly how they came in and out of his day. ( as someone earlier described his experience) Then crash- Dad had a psychotic break and was admitted into care and has not come home. He was trated with Largactil and that drug presented us with a new diagnosis- Lewy body syndrome. I had to search through British Lancet journals to learn about this new diagnosis.Dad is now in care and continues to have some periods of lucidness but his daily experiences are centred in 4 different hallucintory locations- all former life experiences- the war, his workplace, his fishing experiences and his youth. Could anyone help me with an explanation? Mom thinks it is a drug toxicity and will reverse. I explored every possible nutritional and body chemistry state which can present a temporary dementia but of no avail.As I read these posts of this week, I realize so much is unknown but can anyone discuss this dementia due to Lewy body syndome ? Someone posted- is there Lewy bodies in the intestine? To what extent can a depression cause a cognitive impaired response? Dad is only taking Ativan 0,05mgm once a day to assist his caregivers with his personal care. With this post ,I do hope that I have not offended anyone or took a libery that was not mine. I am looking for answers and am turning to this group for counsel. As a daughter, I have begun to offer volunteer time to the PD group locally and in 2 weeks will co- facilitate our 1st meeting with the staff person.( Sons and Daughters of parents with P.D.) Thank you again and will look forward to your responses. Diane Hebert ([log in to unmask]) Burnaby B.C. Canada
