Medication
The following may be needed to make a diagnosis:
- an assessment of symptoms – for example, whether there are typical symptoms of dementia with Lewy bodies
- an assessment of mental abilities – this will usually involve a number of tasks and questions
- blood tests to rule out conditions with similar symptoms
Therapy
Lewy body dementia (LBD) can be difficult to diagnose. Talking to both patients and caregivers helps doctors make a diagnosis. It is important to ask the patient and their care partners about any symptoms involving thinking, movement, sleep, behavior, or mood.
Self-care
There's no cure for Lewy body dementia but many of the symptoms can improve with targeted treatments. Cholinesterase inhibitors.

At what stage of dementia do hallucinations occur?
Hallucinations are caused by changes in the brain which, if they occur at all, usually happen in the middle or later stages of the dementia journey. Hallucinations are more common in dementia with Lewy bodies and Parkinson's dementia but they can also occur in Alzheimer's and other types of dementia.
What are the causes of Lewy body dementia?
The precise cause of LBD is unknown, but scientists are learning more about its biology and genetics. For example, we know that an accumulation of Lewy bodies is associated with a loss of certain neurons in the brain that produce two important chemicals that act as messengers between brain cells (called neurotransmitters).
What are Lewy body dementia signs and symptoms?
People with LBD may not have every symptom associated with the disease. Any sudden or major change in functional ability or behavior should be reported to a doctor.
Types of Lewy body dementia and diagnosis
LBD refers to either of two related diagnoses — dementia with Lewy bodies (DLB) and Parkinson's disease dementia. Both diagnoses have the same underlying changes in the brain and, over time, people with either diagnosis develop similar symptoms. The difference lies largely in the timing of cognitive (thinking) and movement symptoms.
Treatment and care for Lewy body dementia
While LBD currently cannot be prevented or cured, some symptoms may respond to treatment for a period of time. An LBD treatment plan may involve medications, physical and other types of therapy, and counseling. A plan to make any home safety updates and identify any equipment can make everyday tasks easier.
Other treatment considerations
LBD affects the part of the nervous system that regulates automatic actions like blood pressure and digestion. One common symptom is orthostatic hypotension, a drop in blood pressure when standing up that can cause dizziness and fainting.
Lewy body dementia research
Many avenues of research are being explored to improve our understanding of LBD. Some researchers are working to identify the specific differences in the brain between the two types of LBD. Others are looking at the disease's underlying biology, genetics, and environmental risk factors.

The importance of early treatment is supported by recent data suggesting that patients with LBD, might respond better to cholinesterase inhibitors than patients with AD. In addition, an early diagnosis of DLB will help treating physicians know which medications to avoid or use cautiously, especially the antipsychotics (aka neuroleptics).
Is Memantine approved for LBD?
Memantine (Namenda) is another drug (with a different pharmacological mechanism of action) approved for AD but not LBD and is also used off label as an add-on therapy to AChEIs, typically in patients with more severe dementia.

Is dopamine agonist more effective than levodopa?
Dopamine agonists are less effective than levodo pa for treating motor symptoms and are more likely to cause non-motor side effects, especially drug-induced psychosis even at low doses. Dopamine agonists may also cause excessive daytime sleepiness and swelling of the legs.
Is levodopa safe for PD?
Levodopa is an effective and relatively safe drug for treating motor symptoms in PD; most patients with LBD respond with improvement in motor function, without side effects, as long as the dosing is kept at the lowest, most effective level. 5 However, all patients with LBD are vulnerable to the development of medication-induced behavioral or psychotic symptoms. Not everyone with LBD requires anti-parkinsonian treatment, particularly those with DLB. In fact, some patients with DLB may go years before showing signs of parkinsonism. Given the potential for adverse effects, healthcare providers should use levodopa in this setting only when symptoms are truly bothersome and should start with a low dose and titrate up slowly.

What causes LBD?

What is a lewy body?
