Megan Marx, known for her appearance on The Bachelor Australia, has spoken publicly about living with spinocerebellar ataxia (SCA), a rare inherited neurological condition. Her disclosure has brought renewed attention to the medical and functional challenges associated with progressive cerebellar disorders.
Marx first revealed her condition in January 2023 after undergoing genetic testing that confirmed spinocerebellar ataxia. In early 2026, she again discussed her experience in a personal essay for Mamamia, the Bachelor Australia, explaining how the disease continues to affect her daily life.
As reported in People, she wrote,
There is a kind of grief that rarely earns a name. It is not the grief of death, nor even the grief that follows a diagnosis. It is the grief of the life we imagined we might live, and the slow recognition that it will not arrive.

Spinocerebellar ataxia refers to a group of genetic neurodegenerative disorders that primarily damage the cerebellum, the brain region responsible for balance and coordination. In some subtypes, the spinal cord and other neural pathways may also be involved.1
The condition is considered rare, with estimates suggesting it affects approximately 1–5 people per 100,000 population. Most forms follow an inherited pattern, meaning they can run in families.1
Patients with spinocerebellar ataxia typically develop symptoms gradually in adulthood. Early signs often include:
Unsteady gait
Poor hand coordination
Slurred speech
Abnormal eye movements
As the disease advances, individuals may experience increasing difficulty with walking, speaking, and swallowing. The rate of progression varies widely depending on the specific genetic subtype.1
Marx has indicated that her condition may eventually interfere with fundamental physical functions, which is consistent with the known clinical course of many SCA variants.
I carry an awareness of this grief, but I am careful not to let it contain me. I want a life that is workable and free in the ways that matter. That has required deliberate narrowing. In recognition of my neurological disease, and in protection against relapse, I have stripped my life back to what can be sustained.

At present, no curative therapy exists for spinocerebellar ataxia. Management focuses on supportive and symptomatic care. Standard approaches include:
Physiotherapy to maintain mobility
Speech therapy for communication and swallowing support
Occupational therapy to preserve daily function
Regular neurological follow-up
Lifestyle adjustments and assistive devices are often introduced as the disease progresses. Marx has described adapting her routine to focus on manageable activities, which aligns with recommended coping strategies for chronic neurological illness.1
Rare neurodegenerative disorders such as spinocerebellar ataxia often remain underrecognized outside specialist settings. Public disclosures by affected individuals can improve awareness and encourage earlier medical evaluation for symptoms like persistent imbalance or coordination problems, especially in people with a relevant family history.
Spinocerebellar ataxias represent a heterogeneous group of conditions rather than a single disease entity. Ongoing research is investigating genetic mechanisms and potential disease-modifying therapies, but current care remains largely supportive.
Marx’s case highlights the long-term functional adjustments required in progressive cerebellar disorders and underscores the importance of multidisciplinary management.
