Towards a cure for dementia: the role of
axonal transport in Alzheimer’s disease
Richard J Wilson
Abstract
Alzheimer’s disease is an incurable, fatal illness characterised by
years of progressive mental decline. It afflicts half a million people
in the UK - more than any other dementia. The primary risk factor
is old age so this number is rising as we live longer. Current
treatment is palliative while more potent drugs have encountered
problems during clinical trials. It is known that the disease results
from brain deterioration associated with the formation of
microscopic lesions. Genetic mutations cause a small minority of
cases but our knowledge of the underlying biological mechanisms is
limited. The key to improved understanding may be a process vital
to brain cells called axonal transport. Disruption of axonal transport
seems to be an early event in the progression of the disease and is
linked to lesion formation and brain dysfunction so a full
investigation of this process should lead to a cure, if not prevention.
