Clara Health | Join Our ALSP Registry

Join a patient community and registry for those living with Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP)

A new patient-focused foundation is working to connect ALSP patients to the latest research and to a global community.

ALSP diagnosis and symptoms can be overwhelming for patients and their families. Foundations, researchers, and doctors are working together to better understand the cause of ALSP and develop novel treatment options.

Connecting with patient-focused groups can provide you with the support you need and where you can learn more about emerging therapies. To learn more about ALSP, please fill out the interest form below.

Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP)

ALSP is a fatal neurological disease characterized by break down of the white matter in the brain. White matter insulates the wiring that connects neurons and its integrity is critical for proper brain function. Personality changes, including depression and a loss of social inhibition, are among the earliest symptoms of ALSP. Also, some people with ALSP can develop mild seizures. As the disease progresses, patients suffer from a severe decline in cognitive ability. Clinical studies of ALSP points to a loss of one specific cell type in the brain called microglia. Many ALSP patients carry mutations in the CSF1R gene, which is known to regulate microglia function and survival.

About Our Patient-Focused Registry

The goal of this registry

We have two main goals for our registry. 1. To connect patients to a growing community of families, clinicians and the Sisters’ Hope Foundation; and 2. To provide opportunities to patients diagnosed with ALSP for participation in clinical studies.

For ALSP patients: We aim to develop a better understanding of ALSP patients, when they are diagnosed, what their symptoms are, and how we can work with them to better identify potential treatment regimens.

ALSP patient families: We will be focused on providing patient families support, by connecting them with foundation relations, physicians, and researchers who are working to treat ALSP.

Upcoming events

You are invited to a Zoom meeting. When: May 24, 2022 07:00 PM Eastern Time (US and Canada)

Register in advance for this meeting:

"After an ALSP diagnosis many of our families were told there was nothing that could be done but treat the symptoms. All we wanted for our families was a fighting chance, a chance to save future generations. We now have a chance to save our families from this devastating disease by working with industry partners on a cure."
