Amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease involving both upper motor neurons (UMN) and lower motor neurons (LMN). UMN signs include hyperreflexia, extensor plantar response, increased muscle tone, and weakness in a topographic representation. LMN signs include weakness, muscle wasting, hyporeflexia, muscle cramps, and fasciculations. Initial presentation varies. Affected individuals typically present with either asymmetric focal weakness of the extremities (stumbling or poor handgrip) or bulbar findings (dysarthria, dysphagia). Other findings may include muscle fasciculations, muscle cramps, and labile affect, but not necessarily mood. Regardless of initial symptoms, atrophy and weakness eventually affect other muscles. The mean age of onset is 56 years in individuals with no known family history and 46 years in individuals with more than one affected family member (familial ALS or FALS). Average disease duration is about three years, but it can vary significantly. Death usually results from compromise of the respiratory muscles. [from GeneReviews]

Dementia

A loss of global cognitive ability of sufficient amount to interfere with normal social or occupational function. Dementia represents a loss of previously present cognitive abilities, generally in adults, and can affect memory, thinking, language, judgment, and behavior. [from HPO]

Pelizaeus-Merzbacher disease

PLP1-related disorders of central nervous system myelin formation include a range of phenotypes from Pelizaeus-Merzbacher disease (PMD) to spastic paraplegia 2 (SPG2). PMD typically manifests in infancy or early childhood with nystagmus, hypotonia, and cognitive impairment; the findings progress to severe spasticity and ataxia. Life span is shortened. SPG2 manifests as spastic paraparesis with or without CNS involvement and usually normal life span. Intrafamilial variation of phenotypes can be observed, but the signs are usually fairly consistent within families. Female carriers may manifest mild to moderate signs of the disease. [from GeneReviews]

Alzheimer's disease

Alzheimer disease (AD) is characterized by dementia that typically begins with subtle and poorly recognized failure of memory and slowly becomes more severe and, eventually, incapacitating. Other common findings include confusion, poor judgment, language disturbance, agitation, withdrawal, and hallucinations. Occasionally, seizures, Parkinsonian features, increased muscle tone, myoclonus, incontinence, and mutism occur. Death usually results from general inanition, malnutrition, and pneumonia. The typical clinical duration of the disease is eight to ten years, with a range from one to 25 years. Approximately 25% of all AD is familial (i.e., =2 persons in a family have AD) of which approximately 95% is late onset (age >60-65 years) and 5% is early onset (age <65 years). [from GeneReviews]

Frontotemporal dementia

The clinical manifestations of MAPT-related disorders (MAPT-related tauopathies) are most typically those of frontotemporal dementia (FTDP-17), but also include progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), mild late-onset parkinsonism, and dementia with epilepsy. Clinical presentation of frontotemporal dementia (FTD) is variable: some present with slowly progressive behavioral changes, language disturbances, and/or extrapyramidal signs, whereas others present with rigidity, bradykinesia, supranuclear palsy, and saccadic eye movement disorders. Onset is usually between ages 40 and 60 years, but may be earlier or later. The disease progresses over a few years into profound dementia with mutism. PSP is characterized by progressive vertical gaze palsy in combination with a prominent loss of balance at early stages of the disease. With progression, axial rigidity, dysarthria, and dysphagia become prominent, often in combination with a frontal dysexecutive syndrome. CBD is a progressive neurodegenerative disorder which affects both the frontoparietal cortex and the basal ganglia, resulting in a mild to moderate dementia in combination with asymmetric parkinsonism, ideomotor apraxia, aphasia, and an alien-hand syndrome. [from GeneReviews]

Amyotrophic lateral sclerosis type 1

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease involving both upper motor neurons (UMN) and lower motor neurons (LMN). UMN signs include hyperreflexia, extensor plantar response, increased muscle tone, and weakness in a topographic representation. LMN signs include weakness, muscle wasting, hyporeflexia, muscle cramps, and fasciculations. Initial presentation varies. Affected individuals typically present with either asymmetric focal weakness of the extremities (stumbling or poor handgrip) or bulbar findings (dysarthria, dysphagia). Other findings may include muscle fasciculations, muscle cramps, and labile affect, but not necessarily mood. Regardless of initial symptoms, atrophy and weakness eventually affect other muscles.

Parkinsonism

A group of disorders which feature impaired motor control characterized by bradykinesia, MUSCLE RIGIDITY; TREMOR; and postural instability. Parkinsonian diseases are generally divided into primary parkinsonism (see PARKINSON DISEASE), secondary parkinsonism (see PARKINSON DISEASE, SECONDARY) and inherited forms. These conditions are associated with dysfunction of dopaminergic or closely related motor integration neuronal pathways in the BASAL GANGLIA. [from MeSH]

TDP-43 Proteinopathies

Diseases characterized by the presence of abnormally phosphorylated, ubiquitinated, and cleaved DNA-binding protein TDP-43 in affected brain and spinal cord. Inclusions of the pathologic protein in neurons and glia, without the presence of AMYLOID, is the major feature of these conditions, thus making these proteinopathies distinct from most other neurogenerative disorders in which protein misfolding leads to brain amyloidosis. Both frontotemporal lobar degeneration and AMYOTROPHIC LATERAL SCLEROSIS exhibit this common method of pathogenesis and thus they may represent two extremes of a continuous clinicopathological spectrum of one disease. [from MeSH]
