There are some treatments that can help with the symptoms of dementia with Lewy bodies.

Drug treatments for dementia with Lewy bodies

The drugs used to treat Alzheimer's disease may help to improve some of the symptoms of DLB, including problems with thinking skills and visual hallucinations.

These drugs are called:

  • donepezil
  • rivastigmine
  • galantamine
  • memantine.

These drugs boost chemicals that help brain cells to communicate with each other, alleviating some of the memory and thinking symptoms in DLB.

Unfortunately they do not work for everyone, and as symptoms become more severe, they may not work as well.

There are currently no medications available to slow down the progression of DLB but researchers are making progress towards finding lifechanging treatments.

Treatments for agitation and aggression in dementia with Lewy bodies

Agitation and aggression can be common symptoms in dementia.

For people who experience these symptoms a doctor should first assess the person’s health and environment. This could help to identify any causes or triggers of agitation or aggression, so these can be addressed first before trying medication.

A doctor may prescribe drugs called antipsychotics to treat these symptoms. However, people with DLB should be carefully monitored if they are prescribed these drugs as they can cause serious side-effects.

Can you treat movement symptoms in dementia with Lewy bodies?

People who experience problems with movement in DLB can be treated using physiotherapy or with levodopa, a drug used for Parkinson’s disease.

There is a risk that this drug may cause visual hallucinations or confusion symptoms to occur, or to get worse in people who already experience these. Any side effects from medications should be reported to your GP.

For people whose movement symptoms affect them whilst they’re asleep, practical steps, such as moving objects away from the bed, can reduce the risk of injury.

There are also medications available to help people with DLB who have disrupted sleep because of movement.

For general tips around sleep quality your doctor will be able to give you more advice.

Non-drug treatments, such as cognitive therapy, exercise and group activities may also help with some of the symptoms in DLB.

You can discuss your treatment options with your doctor.
