Clinical definition (Orphanet)

A rare neurologic disease characterized by neurodegeneration secondary to repetitive mild traumatic brain injuries. The clinical picture is highly variable and includes behavioral or psychiatric symptoms (such as aggression, depression, delusions, and suicidality), cognitive impairment (including diminished attention, memory deficits, executive functioning deficits, and dementia), and motor deficits (including parkinsonism, , and dysarthria). Neuropathological hallmark is the accumulation of phosphorylated tau-protein in sulci and perivascular regions.

How rare: <1 / 1 000 000 — fewer than one in a million. In a city the size of Kolkata, that might mean on the order of fifteen people.

Research stages

Trial readiness signals

Where this condition sits on an open-data research pipeline — not how close a treatment is, and not medical advice. Empty stages often mean “not in these databases under this Mondo ID,” not “impossible.”

Biology

Genes and phenotypes

Gene–disease validity from GenCC, plus phenotypes and animal models joined from Monarch Initiative via Mondo ID — not a clinical diagnosis aid.

Do we know what causes it?

Not yet — the cause hasn't been pinned down in GenCC.

No strong gene–disease assertion joined for this Orphanet entity.

Phenotypes (Monarch / HPO)

Not enriched in this build — Monarch phenotype joins were not run for this record.

Clinical research

Is a treatment being tested?

20

interventional trials for this specific condition

20 interventional trials matched this specific condition name; 3 currently recruiting in our sample. 2,041 trials are registered for dementia, the broader category — shown separately because they may or may not enrol this specific subtype.

Data as of 27 July 2026

20 interventional trials — more than 73% of diseases in the trials denominator have none at all (5114 of 7003; this disease is at the 94.5th percentile).

Recruiting under the broader category

Observational and natural-history studies

16 observational studies match this condition. These do not test a treatment and are not counted in the interventional-trial headline, but they are genuine research: natural-history work often defines the endpoints needed for a future rare-disease trial, and families may be able to enroll.

Where to find support

We do not yet link condition-specific patient organisations. These umbrella groups support undiagnosed and ultra-rare families:

India — NPRD

Last verified 2026-07-26

This ORPHAcode is not on our curated NPRD list (direct or Mondo-parent match). That does not decide clinical eligibility; families in India should ask a notified Centre of Excellence about current coverage.

Hand-curated for this project. ORPHAcode mappings are best-effort and may be incomplete or imprecise for umbrella categories. Parent (Mondo) matches mean the policy lists a broader category — confirm eligibility with a Centre of Excellence. Financial entitlements summarised from public policy statements and may change. This is not official government guidance.

Confidence reasoning

  • Preferred label is multi-word and distinctive
  • No synonyms dropped by stoplist
  • No label/synonym collisions with other diseases in this corpus
  • Publication count (5603) is implausibly high for prevalence class "<1 / 1 000 000" — treat as possible over-matching, not a measure of research intensity
