Q My mother is experiencing difficulties with her short-term memory. I am becoming increasingly worried that this condition will lead to Alzheimer’s. Can you recommend anything that will help prevent its onset?

A Alzheimer’s is an ageing disorder that affects personality, cognitive function and behaviour, with short-term memory suffering first. The causes are largely unknown, though exposure to toxic metals such as aluminium may play a part. As a precaution, you could ensure that your mother does not use aluminium pans and chooses a natural deodorant that is free of aluminium (a common ingredient in conventional antiperspirants).

Fish has long been recognised as a “brain food”, and the connection between omega-3 fats and cognitive function is well documented. Evidence suggests that inflammation occurs in the brains of dementia patients approximately two years prior to their developing the disease. This could explain why omega-3 fatty acids (found in oily fish, flaxseed, hemp, canola and walnuts), which possess anti-inflammatory properties, have sparked improvements in those showing early symptoms. According to the results of a clinical trial published this year, omega-3 oils may help to slow cognitive decline in mild Alzheimer’s cases, so consuming these on a daily basis is crucial. Try Eskimo-3 oil, a pure oil sourced from wild (not farmed) deep-sea fish, which contains naturally high quantities of EPA and DHA (£12.70 for 105ml, from Nutri; 0800 212742). Take 1 tsp daily.

The rates of Alzheimer’s are much lower among the elderly in India than in the West, and early studies show that curcumin, an antioxidant phytochemical found in turmeric (frequently used in curry), appears to reduce Alzheimer’s-related inflammation in the brain, so include this in cooking. The medicinal mushroom Lion’s Mane (£18.95 for 90 tabs; 0845 650 2266, lemonburst.co.uk) has been shown to regenerate brain tissue and keep cognitive function at peak levels. It is safe to take with other forms of medication. Take two tablets twice daily. Ensure your mother takes other, simple preventive measures, such as going on regular brisk walks, inhaling fresh air deeply and keeping her grey matter active by reading and doing crosswords and puzzles.
