AZHEIMER’S WIFE & CARER STORY: often told but always worth repeating. A full account of the Alzheimer’s carer journey written by Dr Muriel Porter, whose husband developed Alzheimer’s and who is now in an Aged Care Facility (Nursing Home), shut down and unvisited because of covid 19. A story of ongoing grief and courageous coping. https://www.abc.net.au/news/2020-08-29/aged-care-living-with-unmourned-grief/12570328

BLOOD TEST FOR ALZHEIMER’S DISEASE. PROMISING – BUT. The blood test (for P-Tau 217) examined in this research (https://jamanetwork.com/journals/jama/fullarticle/2768841) appears to distinguish Alzheimer’s disease from other common causes of dementia. That is potentially useful for research and could be practically and clinically useful as well, for at least two reasons: (1) to provide a diagnosis – an explanation for a person experiencing problems with functions such as memory or word-finding. (2) to allow early interventions which could stop or slow…..

Using MRI imaging it is now possible to picture in detail the nerve connections between different parts of the brain – the ‘connectome’, the wiring diagram. This Scientific American article describes some studies comparing connections in different animals. One huge seven year study by Yaniv Assef and Yossi Yovel compares the brains of 123 mammalian species. Another by Martijn van den Heuvel compared our brain connections to those of chimpanzees and found that, although we share 255 connections, 33 connections…..

FIVE HEALTHY LIFESTYLE BEHAVIOURS have been found to be associated with a LOWER RISK OF ALZHEIMER’S DISEASE. A recently published study confirms previous evidence that the risk of Alzheimer’s disease is reduced in people who follow some or all of 5 ‘healthy lifestyle’ behaviours: (a) not smoking (b) 150 minutes or more per week of moderate/vigorous-intensity physical activity (c) light to moderate alcohol consumption (d) a MIND diet (see below) and (e) engagement in late-life cognitive activities. https://n.neurology.org/content/early/2020/06/16/WNL.0000000000009816 The MIND…..

ALZHEIMER’S DISEASE LINKED TO CITY POLLUTION?. Cause and effect?. If a cause then what is the mechanism?. More and more recent studies show a strong connection between exposure to airborne particles from car exhausts and Alzheimer’s disease (and possibly Lewy Body disease). The tiny airborne particles (Particulate Matter or PM 2.5), 1/30th diameter of a human hair) probably enter the brain via the nose, olfactory (smell) nerve and olfactory bulb or via a weakened ‘blood-brain barrier’. They may act by…..

HUNTINGTON’S DISEASE (HD) PIONEER, ADVOCATE AND RESEARCHER ACKNOWLEDGES DEVELOPING HUNTINGTON’S HERSELF. Dr Nancy Wexler, PhD, Professor of Neuropsychology, has spent the last 40 years researching, co-ordinating research, campaigning for and initiating care and counselling services for Huntington’s sufferers and their families. In order to further the cause of reducing stigma associated with the diagnosis, she recently acknowledged that she has developed features of this progressive brain disorder. She continues to work. Dr Wexler cared for her mother when her mother…..

PERSONAL EFFECTS OF THIS CORONAVIRUS THING AND COPING WITH IT. A helpful article which frames our response as ‘grief’, as described by Kubler-Ross years ago. “There’s denial, which we say a lot of early on: ‘This virus won’t affect us’. There’s anger: ‘You’re making me stay home and taking away my activities’. There’s bargaining: ‘Okay, if I social distance for two weeks everything will be better, right?’ There’s sadness: ‘I don’t know when this will end’. And finally there’s acceptance……

It has been known for some time that when we hear a song its lyrics are mostly processed on the left side of the brain, while the melody is mostly processed on the right side. Some very recently published research (Phillipe Albouy, Canada) may have clarified how this happens: The auditory (hearing) network on the left is particularly able to analyse the time-based aspects of lyrics. Similar networks on the right side are particularly good at analysing frequencies. We already…..
