Multiple sclerosis (MS) is a chronic disease in which the immune system attacks the protective covering of nerves, leading to communication problems between the brain and the body. Symptoms include fatigue, difficulty walking, numbness, and muscle weakness. MS primarily affects young adults, with women more frequently impacted than men.

Multifocal motor neuropathy (MMN) is a rare disorder characterized by progressive muscle weakness without sensory loss. It primarily affects adults and typically presents with asymmetric weakness in the hands and forearms, often starting on one side.

Migraines are a type of headache disorder that can cause intense throbbing or pulsing pain, often on one side of the head, and may be accompanied by nausea, vomiting, and sensitivity to light and sound. They can affect people of all ages, but often begin in adolescence or early adulthood and are more common in women than men.

Infectious and autoimmune encephalitis (IAE) is an inflammation of the brain caused by viral or bacterial infections, or via the immune system mistakenly attacking brain tissue, affecting people of all ages. It typically presents with symptoms such as fever, headache, confusion, seizures, and changes in personality or behavior.

Hereditary transthyretin-mediated amyloidosis polyneuropathy (hATTR-PN) is a genetic condition where abnormal protein deposits damage nerves, leading to sensory and motor neuropathy. It primarily affects adults and presents with symptoms such as numbness, tingling, muscle weakness, and autonomic dysfunction such as within the digestive or cardiac systems.

Guillain-Barre syndrome (GBS) is a rare neurological disorder where the body’s immune system mistakenly attacks the peripheral nerves, leading to muscle weakness and in some instances, paralysis. It can affect individuals of any age, typically presenting with symptoms such as tingling in the feet and hands, followed by weakness and loss of reflexes.

Dysautonomia is a disorder that affects the autonomic nervous system, leading to problems with heart rate, blood pressure, digestion, and temperature regulation. It can affect people of any age and commonly presents with symptoms like dizziness, fainting, fatigue, and abnormal heart rates.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a neurological disorder characterized by progressive weakness and impaired sensory function in the legs and arms due to nerve damage. It can affect individuals of any age but is more common in adults, often presenting with symptoms such as tingling, numbness, and muscle weakness.

Primary immunodeficiency (Pl) consists of a group of disorders where part of the body’s immune system is missing or functions improperly, leading to increased infections. These disorders can affect individuals of any age, often presenting with frequent, severe, or unusual infections.

Neuroinflammatory disorders are a group of conditions characterized by inflammation of the nervous system, typically affecting the brain and spinal cord, thereby altering their function. These disorders can affect individuals of all ages and often present with symptoms including fatigue, cognitive difficulties, pain, and mobility issues.
