Researchers Propose That Alzheimer's Disease Should be Treated Separately

Neurodegenerative diseases are incurable and debilitating conditions that lead to degeneration or death of cells in the nervous system. A team of scientists has suggested that Alzheimer's disease is probably a collection of diseases that should be treated separately.

Deciphering the mechanism that underlies the development of Alzheimer's disease in certain families but not in others, researchers at the Hebrew University of Jerusalem's Faculty of Medicine have suggested that the malady is actually a collection of diseases that probably should be treated with a variety of different approaches.

Alzheimers Disease

Alzheimer''s disease is a progressive neurodegenerative disease affecting memory and thinking and making the person increasingly dependent on others.

‘Researchers found that the development of distinct neurodegenerative disorders stems from a similar mechanism. They observed that Alzheimer's disease can emanate from more than one mechanism, suggesting that it is actually a collection of diseases that should be classified.’

Conditions such as prion disorders (the most famous of which is 'Mad Cow Disease'), Alzheimer's Disease and Parkinson's Disease share two key features- they emerge as a result of aberrant protein folding and aggregation and their onset is late in life. These maladies emerge either sporadically or as familial, mutation-linked illnesses (certain prion disease can be also infectious).

Since neurodegenerative disorders stem from aberrant protein folding, scientists postulated that an aging-associated decline in the activity of proteins that assist other proteins to fold properly, may be one mechanism that exposes the elderly to neurodegeneration.

Diseases Related to Old Age

Ageing is referred to the accumulation of changes that brings a person closer to death.

Prof. Ehud Cohen said, "This study provides important new insights: first, it shows that the development of distinct neurodegenerative disorders stems from a similar mechanism. More importantly, it indicates that Alzheimer's disease can emanate from more than one mechanism, suggesting that it is actually a collection of diseases that should be classified."

The new insights derived from this research may reinforce the efforts to develop novel therapies to the different subtypes of Alzheimer's disease, providing new hope to those who suffer from this incurable disorder and to their families.

The study appears in EMBO.

Risk Factors for Alzheimers Disease

Cognitively normal adults exhibiting atrophy of their temporal lobe or damage to blood vessels in the brain are more likely to develop Alzheimer's disease.
