Lewi Body Dementia in Seniors

Lewi Body Dementia in Seniors

Lewi Body Dementia is a neurodegenerative disorder that leads to progressive death of nerve cells due to the accumulation of Levi bodies in the cerebral cortex and its other parts. This form of the disease makes up to 20% of all cases of senile dementia and is more common in men.

The causes and pathogenesis of dementia with Levi bodies are not fully understood. Doctors are inclined to believe that hereditary predisposition is the main provocative factor. On average, the duration of the disease is 7 years.

Lewi Body calf dementia may lead to the development of the following syndromes:

Cognitive impairment

Such symptoms are characteristic: a decrease in concentration levels, increased fatigue, unable to think in a rational manner. As a result, patients forget about current affairs, they can repeat the same action many times;

The development of visual-spatial disorders

Patients notice a decrease in vision, so there are difficulties with orientation in space. Patients no longer recognize their relatives;

Changing motor functions

It leads to muscle hyper tone and muscle rigidity, as well as the tremor of the limbs. The patient has a shuffling gait, walking becomes uncertain, and often patients fall even on a flat surface. Therefore, some doctors mistakenly confuse it with Parkinson’s disease;

Visual hallucinations

This syndrome is specific and practically does not occur with other types of dementia. Illusions develop against the background of visual impairment, gradually transforming into full-fledged hallucinations. Hallucinations are often accompanied by delusions;

Sleep disturbance

Patients complain of nightmares that are perceived too real. As a result, in a dream, the patient can fight, scream, mumble, jump and fall out of bed;

Autonomic disorders

These include urinary incontinence, constipation, bradycardia, etc.

Diagnostic measures:

The neurologist may carry out diagnoses on the basis of the clinical picture of the disease, history, and the results of the examination.

There are a number of criteria that allow you to determine the disease with high probability:

The clinical picture of frontal-cortical dementia.

The presence of fluctuations.

Visual hallucinations.


Frequent falls that occur even on flat surfaces.

The presence of intolerance to neuroleptics.

Important: The simultaneous presence of motor and cognitive impairment can cause difficulties during diagnostic activities.
