Early motor symptoms of neurodegenerative diseases often appear in combination with psychiatric symptoms, such as depression or personality changes, and are in danger of being misdiagnosed as psychogenic in young patients. We present the case of a 32-year-old woman who presented with rapid-onset depression, followed by a hypokinetic movement disorder and cognitive decline during pregnancy. Gene...

Progressive multifocal leukoencephalopathy (PML) is a deadly demyelinating disease due to central nervous system replication of the human polyomavirus JC virus (JCV) in immunosuppressed patients. The only effective therapeutic approach is to restore anti-JCV T-cell responses. In this study, we describe a case of rapidly fatal PML with JCV T-cell anergy in a renal transplant patient treated with...

Background Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is a rare autosomal dominant disorder caused by mutations in the colony-stimulating factor 1 receptor (CSF1R) gene. As of 2022, more than 100 different CSF1R were reported patients CSF1R-related leukoencephalopathy. Method In this case report, we described ALSP previously healthy 46-year-old woman. The pa...

BACKGROUND Leukoencephalomyelopathy is an inherited neurodegenerative disorder that affects the white matter of the spinal cord and brain and is known to occur in the Rottweiler breed. Due to the lack of a genetic test for this disorder, post mortem neuropathological examinations are required to confirm the diagnosis. Leukoencephalopathy with brain stem and spinal cord involvement and elevated ...

BACKGROUND Cocaine abuse is associated with several mechanisms of brain injury including ischemic, hemorrhagic and metabolic. Recently two case reports of leukoencephalopathy in cocaine users implicated a commonly used cocaine adulterant, levamisole. One well-documented adverse effect of levamisole, when used alone as antihelminthic or immunomodulatory drug, is multifocal inflammatory leukoence...

BACKGROUND Rituximab is a recombinant chimeric monoclonal antibody against CD20, a molecule expressed on cells of the B-cell lineage. A phase 2 clinical trial recently provided strong evidence of the beneficial effects of rituximab in patients with relapsing-remitting multiple sclerosis. We and other investigators previously demonstrated that rituximab therapy depletes B lymphocytes from periph...

Progressive multifocal leukoencephalopathy (PML) is a rare, myelin-damaging disease of the central nervous system (CNS) in a setting of immunosuppression that is superimposed by concurrent autoimmune diseases such as multiple sclerosis and AIDS or simultaneous administration of immune modulatory monoclonal antibody drugs such as natalizumab. The causative agent is a Polyomavirus known as John C...

Treatment of progressive multifocal leukoencephalopathy (PML) in a patient with exogenous immunosuppression starts with discontinuation of immunosuppressive medication. The restored host immunity will clear JC virus, the cause of PML, from the brain via cell-mediated immune mechanisms. Patients with solid-organ transplants will lose the transplanted organ, however, and patients who have autoimm...
