Dementia: Scientists at Oxford University discover ‘neurotoxic’ chemical causes dementia

In previous years, dementia was considered an inevitable part of aging, something that happens as someone gets older. Today the world is different, today’s science tells us dementia is a disease, and a disease that can be treated. Researchers at biotech company Neuro-Bio say they have discovered what could be the first effective treatment for dementia after they discovered a chemical ‘ neurotoxicity’ causes this disease. If this treatment is implemented, it could bring relief to thousands of patients living with the disease.

One of the scientists behind the study, Baron Susan Greenfield, said the study will lead to a paradigm shift in how the condition is treated.

Baron Greenfield said: “Most scientists have long believed that amyloid plaques are the cause of the disease. But we believe that amyloid plaques accumulate well after brain degeneration begins. “

The reason why other treatments haven’t been successful, says Greenfield, is because “by the time you see the patches, the horse has already started.”

Neuro-Bio’s treatment focuses on cells in the center of the brain called the isodendritic core; In patients with Alzheimer’s disease, these are the cells that usually start to die first.

Although the scientists don’t know why this process begins, Neuro-Bio says they have found the molecule responsible for the snowballing effect of dead cells.

The molecule in question is called T14 and Neuro-Bio’s drug, given as a nasal spray, aims to limit the damage caused by the molecule.

“Until we know a drug that is safe and effective in humans, it’s too early to get excited,” said Robert Howard, Professor of Aging Psychiatry at UCL. But the truth is that amyloid drugs don’t have the positive effects the Alzheimer’s community hopes they will. ”

Alzheimer’s is the most common form of dementia in the UK.


Although there is no cure, an early diagnosis is better than a late diagnosis: “early diagnosis means its progress can be slowed in some cases, so the person can maintain function. their psyche longer.

“Diagnosis helps people with dementia get appropriate treatment and support.

“With treatment and support, many people can live active and satisfied lives with dementia.”
