Dementia is the name for problems with mental abilities caused by gradual changes and damage in the brain. 2009), because it is increasingly clear that abnormal α-synuclein accumulation in neuronal perikarya may be the tip of the iceberg, with evidence of accumulation not only in neuronal cell processes (Irizarry et al. Two or more of these pathologies commonly coexist in the same individual. The combination of Lewy bodies and Lewy neurites is sometimes referred to as Lewy-related pathology (Dickson et al. It is characterized pathologically by Lewy bodies (LBs), Lewy neurites, and neuronal loss in the substantia nigra and other subcortical nuclei. Although fPD cases account for less than 10% of all PD in the general population, abnormal accumulation of αS is present in virtually all patients with PD and related synucleinopathies.

While they are characterized by different clinical profiles, attentional deficits are . Microscopic. In the patient brain, αS-rich lesions can be found in neuronal somata (Lewy bodies, LBs) and in neurites (Lewy neurites, LNs). However, DaTscan can help differentiate dementia with Lewy bodies from other forms of dementia. No standard criteria exist for the neuro-pathologic diagnosis of Parkinson disease dementia, as Objectives To investigate survival among elderly residents of Swedish nursing homes (NHs), with specific focus on those with two or more signs of Lewy body dementia (LBD). α-Synucleinopathies (ASP) are progressive, adult-onset neurodegenerative diseases that include Parkinson's disease (PD), dementia with Lewy bodies (DLB) and multiple system atrophy (MSA) (Spillantini and Goedert, 2000, Goedert, 2001, Beyer and Ariza, 2007).The main pathological hallmark of these diseases is the occurrence of hyperphosphorylated, misfolded and fibrillized α . Studies Liver, Clinical Sciences, and Ancient economy. Protein deposits, called Lewy bodies, develop in nerve cells in the brain regions involved in thinking, memory and movement (motor control). Dementia with Lewy bodies General. b. mutations in the alpha-synuclein gene cause doubling or even tripling of encoded gene, leading the cell to make an overabundance of proteins. Multiple system atrophy (MSA) Definition: rare, adult-onset, neurodegenerative disease characterized by neuronal degeneration in the substantia nigra . 1 , 2 It is unclear whether this is simply coincidental, evidence of a shared diathesis, or indicative of interaction between the pathoetiologic cascades of these diseases. It's rare in people under 65. Further confusing the issue, an autopsy study by Schneider et al. Lewy bodies (LBs) of Parkinson's disease (PD) and glial cytoplasmic inclusions (GCIs) of multiple system atrophy (MSA) are pathological deposits containing phosphorylated α-synuclein as one of their major constituents [].These diseases are grouped under the name "synucleinopathies" based on the assumption that LBs and GCIs share common mechanism for α-synuclein deposition []. Generic terms such as Lewy body (LB) disease are often helpful. The most common symptoms include changes in thinking, behavior, movement, and sleep. Design Prospective observational study.
