Huntington’s disease: three conditions in one body, and a whole family in the room

Huntington’s produces a movement disorder, a cognitive decline and a psychiatric illness at the same time, in the same person, for fifteen to eighteen years — which is why Australian services, organised to treat one thing at a time, handle it so badly. A family quoted in Australian research put it in eleven words: too young for aged care, but too impaired to live at home. In 2019, 331 Australians with HD were in permanent residential aged care and 149 of them were under 65. These guides cover the parts that are genuinely different: why standard cognitive screens come back normal in a person who cannot run their own life, why generic behaviour support reliably fails here, why the dietary advice runs opposite to everything else in medicine, and the Australian law that changed on 8 October 2026, when life insurers lost the right to use genetic test results. Written by a registered NDIS provider. Figures are cited to their sources, and we flag the places where the Australian evidence simply does not exist.

The condition, the gene, and the test

Huntington’s is three conditions in one body, inherited by half of every affected person’s children. These four guides cover what it is, how the genetics works, and the Australian law that changed in October 2026.

Movement, thinking and mood — and why they don’t move together

The psychiatric symptoms do not progress in step with the motor and cognitive decline, so the stage of the chorea tells you almost nothing about how hard the rest will be.

If you read nothing else here

Two things that are nearly always got wrong

The first is that Huntington’s gets read as a movement disorder, because the chorea is the visible part. It is not what drives support need. Executive impairment, apathy and irritability are what cost people their jobs, their relationships and their housing, and they are invisible in a one-hour assessment by somebody who does not know what to look for — which is why so many HD plans fund equipment for a person whose real need is a human being to start things. The second is that generic positive behaviour support, built on teaching the person a replacement strategy, does not work in a condition that has damaged learning, flexibility and insight. Plans built that way fail and then record the person as non-compliant.

Ring Huntington’s Australia on 1800 244 735. Free, national, and the organisation that knows what exists in your state — peer support, specialist services, and practitioners who have actually worked with this condition. Ask your neurologist for referral to a specialist HD clinic: Westmead or John Hunter in NSW, Royal Brisbane and Women’s in Queensland, Flinders in South Australia, Royal Melbourne’s Neuropsychiatry Centre or Calvary Health Care Bethlehem in Victoria, North Metropolitan Health Services in WA, and Older Persons Mental Health in Tasmania. The ACT and Northern Territory have no listed HD clinic, so families there generally work with an interstate service. Genetic counselling is free through state genetic services, for the whole family, and having the appointment commits you to nothing. And Carer Gateway is on 1800 422 737 — separate from the person’s own funding, and most carers have never heard of it.

Questions the guides don’t answer?

We support people with Huntington’s who are NDIS participants — personal care, overnight and 24-hour support at home, supported independent living, and behaviour support built for this condition rather than the generic version. Most people with HD are diagnosed between 30 and 50, so the NDIS is usually the right system; we hold no aged care approval, so for somebody over 65 outside the scheme we will say so and point you to My Aged Care on 1800 200 422. Ten minutes on the phone either way, no obligation, and we will tell you if another provider is the better fit.
