COLLABORATION WORKING IN OLDER PERSONS MENTAL HEALTH, AGED AND DEMENTIA CARE. “Raise Your Voice’ – A thought provoking and stimulating conference from the PGNA on Friday, 13th September in Wollongong.

He will present some information on: anxiety, depression, hallucinations, delusions and confabulations associated with…..
The fibres/tracts/connections shown in the beautiful pictures in the link below are often affected in older people by damage to microscopic arteries (arterioles) in the brain. This can contribute to depression and to neurocognitive problems, including dementia. (page 275 and pages 455-458 in my book). The ABC Science article provides a nice account of the way these pictures are produced, indirectly, via mathematical analysis from MRI imaging. Knowing about these connections can help us to understand how brain systems (rather…..
Judgment depends on memory. New research appears to show that remembering task and decision-making sequences involves a later replay of those processes directed by a structure in the brain called the hippocampus. Replay in the hippocampus is critical to forming memories but also to learning which of our behaviours and decisions are most effective at accomplishing a particular or perhaps related goal. The hippocampus is damaged in Alzheimer’s disease and usually in Alcohol Related Brain Disease. This process of ‘replay’…..
The link below is to an article which nicely outlines three important presentations of Frontotemporal Dementia (FTD) – a common form of early onset dementia – dementia which affects people in their 50s and 60s: Behavioural variant FTD; Language variant FTD; Amyotrophic Lateral Sclerosis (motor neurone disease) with FTD. Or read about it in Your Brain in Sickness and in Health: page 66 and descriptions/explanations elsewhere in the book of particular issues with this disorder such as deterioration in social…..
A person experiencing dementia may easily become overwhelmed and flustered. They may then have even greater difficulty than usual with remembering, with managing tasks and with functioning independently. They may become very anxious, angry, ashamed or distressed in other ways. The heightened emotion can then further interfere with their ability to ‘think straight’, to function well, and a ‘vicious cycle or circle’ may set in. This has been called a ‘catastrophic reaction’ and is discussed in Chapter 4 of my…..
Another cause of severe memory loss, particularly affecting people over 80 years of age, has been found. So the known causes of the disorders called dementia are now believed to be: Alzheimer’s disease, Vascular dementia, Dementia with Lewy bodies, ‘LATE’ (the newly understood cause) and, importantly various mixtures of these brain disorders. You can read about it in a CNN post: https://edition.cnn.com/2019/04/30/health/dementia-late-alzheimers-study/index.html or in detail in an article in the journal Brain.
The drug ‘aducanumab’ showed great promise in removing amyloid from the brains of people with Alzheimer’s disease. Amyloid deposits (‘plaques’) have been thought, perhaps incorrectly, to be the cause of brain deterioration in Alzheimer’s disease. But preliminary analysis of results from an incomplete very large trial did not show enough improvement to justify continuing the trial.

Korsakoff syndrome, usually associated with alcohol abuse can occur without alcohol intake at all. It is due to a deficiency of thiamine (Vitamin B1). Other conditions where it can be a problem include: anorexia-bulimia nervosa; severe and persistent vomiting (pregnancy, chemotherapy); after gastric banding; associated with Cancer or other causes of malnutrition or subnutrition. It is discussed (as Wernicke-Korsakoff state) on pages 94, 104, 353-4 in Dr Sid’s book. http://www.jneuropsychiatry.org/abstract/a-case-of-nonalcoholic-korsakoff-syndrome-resulting-from-malnutrition-due-to-selfneglect-and-severe-depression-12799.html
Excerpt: ‘The book has universal appeal; while dealing with complex issues, it is written in plain English; it will help, guide and comfort families of those who have a brain disorder; it is instructive for the family or general physician; and there is much that will interest even the most widely read student of psychology or psychiatry’ Australasian Psychiatry 2017 Vol 25(6) 630-632 https://doi.org/10.1177/1039856217726698
