What are the symptoms of Lewy Body Disease?


Accueil > Elderly Health Care > Lewy body disease

Lewy body disease, also known as Lewy body dementia (LBD), is a complex and often challenging neurological condition. It's characterized by the presence of abnormal protein deposits in the brain, known as Lewy bodies. This condition shares features of both Alzheimer's and Parkinson's diseases, making it a unique and sometimes perplexing disorder. Let's explore some of the common symptoms associated with Lewy body disease.

1. Cognitive changes:

  • Fluctuating cognitive abilities: People with LBD often experience unpredictable fluctuations in their cognitive abilities. These can range from relatively normal cognitive function to significant impairment within the same day or even hour.
  • Memory loss: Memory problems are common and can affect both short-term and long-term memory. Individuals may struggle to remember recent events or important details from their past.
  • Attention and alertness: Difficulty with sustained attention and alertness can lead to disorganized thinking and problems with problem-solving and decision-making.

2. Visual hallucinations:

Visual hallucinations are a hallmark symptom of Lewy body disease. Individuals may see people, animals, or objects that aren't there. These hallucinations can be vivid and detailed.

3. Motor Symptoms:

LBD often presents with motor symptoms similar to Parkinson's disease, including:

  • Tremors: Involuntary shaking or trembling of the hands, arms, or legs.
  • Bradykinesia: Slowness of movement.
  • Stiffness: Muscle rigidity, making movement difficult.
  • Balance and Coordination Problems: Difficulty maintaining balance and coordination, leading to falls.

4. Sleep Disturbances:

Sleep disturbances are common, with individuals experiencing problems such as vivid nightmares, acting out dreams (known as REM sleep behavior disorder), and excessive daytime sleepiness.

5. Behavioral and Psychiatric Symptoms:

LBD can cause changes in behavior and mood, including depression, anxiety, agitation, and irritability.

6. Sensitivity to Medications:

Individuals with LBD can be especially sensitive to certain medications, particularly antipsychotic drugs, which can worsen their symptoms.

7. Autonomic Nervous System Dysfunction:

LBD can impact the autonomic nervous system, leading to issues like orthostatic hypotension (a sudden drop in blood pressure upon standing), constipation, and urinary problems.

8. Delusions:

Some individuals may experience false beliefs or delusions, often paranoid or grandiose in nature.

It's important to note that while these symptoms are common in LBD, the presentation of the disease can vary from person to person. Additionally, LBD is challenging to diagnose and often requires the expertise of a neurologist or specialist in the field.

Caring for someone with Lewy body disease can be demanding, and it's essential to seek support from healthcare professionals, support groups, and caregivers who have experience with this unique condition. By recognizing the symptoms and seeking appropriate care, individuals and their families can better manage the challenges associated with Lewy body disease.
