Like other forms of Dementia, it has its own range of symptoms. One of these symptoms affects your sight.

People with Lewy Body dementia may suffer from hallucinations.

They may hear, see, or smell things that are not there.

Visual hallucinations are one of the most common symptoms of Lewy body dementia.

A symptom of this form of dementia includes a symptom that is also found in another form of dementia, Alzheimer’s.

People suffering with Lewy body dementia may find it increasingly difficult to understand what’s happening around them.

They may find it harder to think clearly and to remember, although memory loss is more common in those with Alzheimer’s than this particular form of dementia.

As well as this, Lewy body patients may suffer from periods of confusion or sleepiness that can range from a few minutes to a number of hours.

Patients may also suffer from stiffness in their limbs and slow movements as the messages from their brains becomes disrupted by the condition.

In common with Parkinson’s disease, tremors (the inability to stop shaking) are a further symptom of Lewy Body dementia.

Sleep may be disturbed too.

People with Lewy Body dementia experience disturbed sleep, occasionally bursting out in shouting and violent movements.

Furthermore, other symptoms include suffering fainting spells and feeling unsteady on your feet.

It’s not just your physical movements that are affected, there could be signs in their mental health too.

As well as marked swings between being confused and alert, the sufferer may develop depression as a result.

Whilst dementia is ultimately fatal, there are medicinal treatments that can be taken to try to ease the decline.

Acetylcholinesterase inhibitors can help fight the hallucinations, reduce sleepiness and clear the confusion in some patients.

Memantine can be used to block the effect of a neurotoxin (poison that attacks the nervous system) in the brain called glutamate.

Other medicines that can help to temporarily control some of the symptoms include antidepressants and antipsychotics.

Lewy Body dementia, like other forms of dementia is most common in over-65s.
