What is dementia with lewy bodies?

Classification. Dementia with Lewy bodies (DLB) is a type of dementia, a group of diseases involving progressive neurodegeneration. In other words, it is characterized by degeneration of the central nervous system that worsens over time. Dementia with Lewy bodies can be classified in other ways.

What is DLB in dementia?

DLB is dementia that occurs with "some combination of fluctuating cognition, recurrent visual hallucinations, rapid eye movement (REM) sleep behavior disorder (RBD), and parkinsonism starting with or after the dementia diagnosis", according to Armstrong (2019). DLB has widely varying symptoms and is more complex than many other dementias. Several areas of functioning can be affected by Lewy pathology, in which the alpha-synuclein deposits that cause DLB damage many different regions of the nervous system (such as the autonomic nervous system and numerous regions of the brain).

What are supportive features of DLB?

Supportive features of DLB have less diagnostic weight, but they provide evidence for the diagnosis. Supportive features may be present early in the progression, and persist over time; they are common but they are not specific to the diagnosis. The supportive features are: 1 marked sensitivity to antipsychotics (neuroleptics); 2 marked dysautonomia (autonomic dysfunction) in which the autonomic nervous system does not work properly; 3 hallucinations in senses other than vision ( hearing, touch, taste, and smell ); 4 hypersomnia (excessive sleepiness); 5 hyposmia (reduced ability to smell); 6 false beliefs and delusions organized around a common theme; 7 postural instability, loss of consciousness, and frequent falls; 8 apathy, anxiety, or depression.

How does DLB affect quality of life?

Relative to AD, DLB generally leads to higher disability, lower life expectancy and a reduced quality of life, with increased costs of care. Depression, apathy, and visual hallucinations contribute to the reduced quality of life. Decline may be more rapid when severe visuospatial deficits show up early in the course of the Lewy body dementias, when the APOE gene is present, or when AD—or its biomarkers—is also present. The severity of orthostatic hypotension also predicts a worse prognosis.

When was presenile dementia first described?

Archived from the original on July 16, 2020. Retrieved September 8, 2020. In 1976, Kenji Kosaka and colleagues described the first post-mortem case of presenile dementia with 'Lewylike-bodies' pathology and, in 1984, Kosaka introduced the term 'diffuse Lewy body disease'.

Who discovered protein deposits in the brain?

Frederic Lewy (1885–1950) was the first to discover the abnormal protein deposits in the early 1900s. In 1912, studying Parkinson's disease ( paralysis agitans ), he described findings of these inclusion bodies in the vagus nerve, the nucleus basalis of Meynert and other brain regions. He published a book, The Study on Muscle Tone and Movement. Including Systematic Investigations on the Clinic, Physiology, Pathology, and Pathogenesis of Paralysis agitans, in 1923 and except for one brief paper a year later, never mentioned his findings again.

Is DLB inherited?

The heritability of DLB is thought to be around 30% (that is, about 70% of traits associated with DLB are not inherited). There is overlap in the genetic risk factors for DLB, Alzheimer's disease (AD), Parkinson's disease, and Parkinson's disease dementia. The APOE gene has three common variants.
