How can you tell the difference between Lewy body dementia and Alzheimer's?

Alzheimer's affects the brain's ability to store new information in the form of memories, while Lewy body dementia targets a different set of cognitive functions - specifically problem-solving and reasoning. Hallucinations occur early in Lewy body dementia but only after about four years in Alzheimer's disease.

What is the life expectancy with Lewy body dementia?

The life expectancy of individuals with dementia with Lewy bodies varies; people typically survive about 5 to 7 years after they are diagnosed. REM sleep behavior disorder may be the first sign of dementia with Lewy bodies. It can occur years before other symptoms appear.

What is the best medication for Lewy body dementia?

Acetylcholinesterase inhibitors

Acetylcholinesterase (AChE) inhibitors, such as donepezil (Aricept), rivastigmine (Exelon) and galantamine (Reminyl), may help improve hallucinations, confusion and sleepiness in some people.

What are the signs of end stage Lewy body dementia?

In the later stages of Lewy body dementia, extreme muscle rigidity and sensitivity to touch develops. 4 People need assistance with almost all activities of daily living. Speech is often very difficult and maybe whispered. Some people stop talking altogether.

What kills a person with Lewy body dementia?

Causes of death in PD are similar to those in non-PD cohorts, particularly for mild to moderate PD [10], whereas individuals with Lewy body dementia commonly die from dementia-related complications and have more than double the likelihood of respiratory death as those with AD dementia [11].

Why is Lewy body dementia fatal?

Like others with LBD, muscle weakness may affect his swallowing ability. This can lead to aspirating food or liquid, resulting in pneumonia, a common cause of death in advanced dementia. Even without problems with aspiration, he'd probably succumb to pneumonia or heart failure after months of being bedridden.

Can you live alone with Lewy body dementia?

Because there is no cure, treatment for LBD is about symptom management. If you have LBD, live alone, and want to remain independent for as long as possible, it's important to establish a plan that will help you to care for yourself.

What is the interlocking finger test for dementia?

The interlocking finger test (ILFT) is a bedside screening test in which the subject must imitate four bimanual finger gestures without symbolic meaning.

Does Lewy body dementia run in families?

Disease at a Glance

Lewy body dementia usually occurs sporadically in people with no family history of the condition. Rarely, more than one family member may be affected."

What stage of dementia is hallucinations?

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 type of dementia progresses rapidly?

Rapidly progressive dementias (RPDs) are dementias that progress quickly, typically over the course of weeks to months, but sometimes up to two to three years. RPDs are rare and often difficult to diagnose. Early and accurate diagnosis is very important because many causes of RPDs can be treated.

How long can an 80 year old live with dementia?

Life expectancy is less if the person is diagnosed in their 80s or 90s. A few people with Alzheimer's live for longer, sometimes for 15 or even 20 years.

What type of dementia is hereditary?

This is called Familial Alzheimer's disease (FAD). If a parent has a mutated gene that causes FAD, each child has a 50% chance of inheriting it. The presence of the gene means that the person will eventually develop Alzheimer's disease, usually in their 40s or 50s.

What causes Lewy bodies to form?

Lewy bodies disease is a form of dementia caused by the decay of brain tissues. This decay is caused by the build up of abnormal proteins called Lewy bodies, which are also found in people with Alzheimer's disease and Parkinson's disease.

What stage is dementia crying?

Sadness and Crying

As Alzheimer's progresses, your loved one may start to behave differently. They may feel sad and cry more often. Crying about little things is common in certain types of dementia because those little things affect areas of the brain that control emotions.

Does Lewy body dementia progress fast?

Unlike Alzheimer's disease, which tends to progress gradually, this disease often starts rapidly, with a fast decline in the first few months. Later, there may be some leveling off but Lewy body dementia typically progresses faster than Alzheimer's. A patient can survive from five to seven years with the disease.
