Scientist want to test whether CBD treatment can help reduce the effects of Sundowners Syndrome

Alzheimer’s Research is funding a trial into whether a new CBD based drug can help ease these changes.

The cannabis-based drug is currently licensed for use in the UK for treating patients with MS.

Scientists from King’s College London are now recruiting volunteers with Alzheimer’s who are living in care homes and have symptoms of agitation.

Participants will take the medication for four weeks or a placebo.

Researcher Prof Dag Aarsland, an Old Age Psychiatrist, said: “Many people with Alzheimer’s can become agitated or aggressive, and this can pose difficulties for the person with the condition and those closest to them.

“Current treatments for behavioural and psychiatric symptoms of dementia are very limited, and we desperately need to develop alternatives.

“Doctors sometimes prescribe anti-psychotic medications, and while these drugs can have important benefits, these need to be weighed against the risk of very serious side effects.”
