Functional Neurological Symptom Disorder (FNSD) is a condition where individuals experience real neurological symptoms—such as weakness, tremors, or seizures—without any detectable structural or ...
Sjögren–Larsson syndrome is a rare, inherited disorder that affects both the skin and the nervous system. It arises because of a deficiency of the enzyme fatty aldehyde dehydrogenase (FALDH), caused ...
Congenital Myasthenic Syndromes (CMS) are a group of inherited disorders affecting the safety and reliability of signal transmission at the neuromuscular junction, where nerves meet muscle fibers. In ...
Progressive Supranuclear Palsy (PSP) is a rare, progressive neurodegenerative disorder characterized by the abnormal accumulation of tau protein in certain brain regions, leading to widespread ...
Abducens nerve palsy is a condition in which the sixth cranial nerve (the abducens nerve) does not function properly, leading to weakness or paralysis of the lateral rectus muscle. This muscle is ...
Mixed sensory-autonomic ganglionopathy (MSAG) is a rare disorder in which both sensory and autonomic ganglia—the nerve cell clusters responsible for transmitting sensory information (touch, pain, ...
Small-fiber sensory ganglionopathy (SFSG) is a rare disorder characterized by selective injury to the cell bodies (ganglia) of the small-diameter sensory neurons in the dorsal root ganglia (DRG), ...
Large-fiber sensory ganglionopathy, also known as sensory neuronopathy, is a disorder in which the sensory neurons located in the dorsal root ganglia—the clusters of nerve cell bodies along the ...
Vasculitic Sensory Ataxic Neuropathy is a rare form of peripheral nerve injury in which inflammation of the small blood vessels (vasculitis) supplying the sensory nerves leads to loss of ...
Sarcoidosis-related sensory neuropathy is a form of peripheral nerve damage that arises as a complication of sarcoidosis, a multisystem granulomatous disease. In sarcoidosis, clusters of inflammatory ...
POEMS syndrome is a rare multisystem disorder caused by an underlying plasma cell disorder. The name “POEMS” stands for Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy, and Skin ...
Hereditary demyelinating sensory neuropathies are a group of inherited disorders in which the protective myelin sheath surrounding sensory nerve fibers is damaged due to genetic mutations. This ...
Paraneoplastic sensory ataxic neuropathy (PSAN) is a rare neurological condition that arises as an indirect effect of cancer elsewhere in the body. It is “paraneoplastic” because the immune system, ...
Chronic Sensory Ataxic Neuropathy with Anti-Disialosyl IgM Antibodies (often abbreviated as CANDA) is a rare, immune-mediated peripheral nerve disorder characterized by a slowly progressive loss of ...
Distal Acquired Demyelinating Symmetric (DADS) neuropathy is a chronic, immune-mediated disorder of the peripheral nerves characterized by symmetrical loss of myelin (the insulating sheath around ...
Sensory-predominant chronic inflammatory demyelinating polyradiculoneuropathy is an autoimmune disorder in which the body’s immune system attacks the myelin sheath of peripheral sensory nerves more ...
