1.

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]

MedGen UID:
99229
Concept ID:
C0497327
Finding; Mental or Behavioral Dysfunction
2.

Neurodegenerative disease

Hereditary and sporadic conditions which are characterized by progressive nervous system dysfunction. These disorders are often associated with atrophy of the affected central or peripheral nervous system structures. [from MeSH]

MedGen UID:
101195
Concept ID:
C0524851
Disease or Syndrome
3.

Neurofibrillary tangles

Abnormal structures located in various parts of the brain and composed of dense arrays of paired helical filaments (neurofilaments and microtubules). These double helical stacks of transverse subunits are twisted into left-handed ribbon-like filaments that likely incorporate the following proteins: (1) the intermediate filaments: medium- and high-molecular-weight neurofilaments; (2) the microtubule-associated proteins map-2 and tau; (3) actin; and (4) UBIQUITINS. As one of the hallmarks of ALZHEIMER DISEASE, the neurofibrillary tangles eventually occupy the whole of the cytoplasm in certain classes of cell in the neocortex, hippocampus, brain stem, and diencephalon. The number of these tangles, as seen in post mortem histology, correlates with the degree of dementia during life. Some studies suggest that tangle antigens leak into the systemic circulation both in the course of normal aging and in cases of Alzheimer disease. [from MeSH]

Cell or Molecular Dysfunction; Finding

Familial dysautonomia

Familial dysautonomia (FD) affects the development and survival of sensory, sympathetic, and parasympathetic neurons. It is a debilitating disease present from birth. Neuronal degeneration progresses throughout life. Affected individuals have gastrointestinal dysfunction, vomiting crises, recurrent pneumonia, altered sensitivity to pain and temperature perception, and cardiovascular instability. About 40% of individuals have autonomic crises. Hypotonia contributes to delay in acquisition of motor milestones. Older individuals often have a broad-based and ataxic gait that deteriorates over time. Life expectancy is decreased. [from GTR]

MedGen UID:

Concept ID:
C0013364
Congenital Abnormality; Disease or Syndrome
5.

Neurodegeneration

Loss of functional activity and trophic degeneration of nerve axons and their terminal arborizations following the destruction of their cells of origin or interruption of their continuity with these cells. The pathology is characteristic of neurodegenerative diseases. Often the process of nerve degeneration is studied in research on neuroanatomical localization and correlation of the neurophysiology of neural pathways. [from MeSH]

MedGen UID:
17999
Concept ID:
C0027746
Cell or Molecular Dysfunction
6.

Neurocognitive disorder

A disorder characterised by a decline primarily in intellectual function due to disease of the brain caused by a variety of acquired conditions such as cerebrovascular disease, Alzheimer's disease, infections, adverse drug reactions and trauma. [from SNOMEDCT_US]

MedGen UID:
873945
Concept ID:
C4041080
Mental or Behavioral Dysfunction
7.

Tauopathy

Neurodegenerative disorders involving deposition of abnormal tau protein isoforms (TAU PROTEINS) in neurons and glial cells in the brain. Pathological aggregations of tau proteins are associated with mutation of the tau gene on chromosome 17 in patients with ALZHEIMER DISEASE; DEMENTIA; PARKINSONIAN DISORDERS; progressive supranuclear palsy (SUPRANUCLEAR PALSY, PROGRESSIVE); and corticobasal degeneration. [from MeSH]

MedGen UID:
181880
Concept ID:
C0949664
Disease or Syndrome
8.

Diagnosis, Psychiatric

MedGen UID:
138165
Concept ID:
C0376338
Mental or Behavioral Dysfunction
9.

Unspecified encephalopathy

A functional and/or structural disorder of the brain caused by diseases (e.g. liver disease, kidney disease), medications, chemicals, and injuries. [from NCI]

MedGen UID:
39314
Concept ID:
C0085584

Psychoses, Traumatic

MedGen UID:
19557
Concept ID:
C0033943
Mental or Behavioral Dysfunction
11.

Disorder of nervous system

A non-neoplastic or neoplastic disorder that affects the brain, spinal cord, or peripheral nerves. [from NCI]

MedGen UID:
14336
Concept ID:
C0027765
Disease or Syndrome
12.

Disorder of brain

A non-neoplastic or neoplastic disorder that affects the brain. [from NCI]

MedGen UID:
14214
Concept ID:
C0006111
Disease or Syndrome
13.

Mental disorder

A disorder characterized by behavioral and/or psychological abnormalities, often accompanied by physical symptoms. The symptoms may cause clinically significant distress or impairment in social and occupational areas of functioning. Representative examples include anxiety disorders, cognitive disorders, mood disorders and schizophrenia. [from NCI]

MedGen UID:
14047
Concept ID:
C0004936
Mental or Behavioral Dysfunction
