Amyloid plaque reduction with aducanumab: example amyloid PET images at baseline and week 54. Axial slice shows anatomical regions in posterior brain putatively related to Alzheimer’s disease pathology

The researchers furthermore demonstrated in an early stage clinical study that, after 1 year of treatment with Aducanumab, cognitive decline could be significantly slowed in antibody-treated patients as opposed to the placebo group. Although the causes of Alzheimer’s disease are still unknown, it is clear that the disease commences with progressive amyloid deposition in the brains of affected persons between 10 to 15 years before the emergence of initial clinical symptoms such as memory loss...

Numerous epidemiological studies have revealed profitable effects of dietary intake of especially fish oil on cognitive decline during aging and dementia. One of the invariable pathologies in AD is degeneration of cholinergic synapses in brain cortex and hippocampus. Current pharmacological interventions are limited to a few drugs that alleviate symptoms but do not slow down the underlying disease processes eg inhibitors of cholinesterases, enzymes that degrade the neurotransmitter acetylcholine, or memantine, a modulator of glutamate neurotransmission.

Within the EU-funded project LipiDiDiet (FP7-211696, the...
