Myotonic dystrophy
Myotonic dystrophy is an autosomal dominant genetic disorder characterized by progressive muscle weakness, muscle atrophy, and myotonia (inability to relax muscles promptly after voluntary or passive contraction). Clinical manifestations primarily include skeletal muscle weakness, muscle atrophy or stiffness, cardiac conduction abnormalities, cataracts, and infertility.
View detailsSleep-wake rhythm disorder
Sleep-wake rhythm disorder refers to a condition where an individual's sleep-wake rhythm does not align with the rhythm followed by most people in their environment. It manifests as insomnia during the main sleep period and hypersomnia during the period when one should be awake.
View detailsSubclavian steal syndrome
Subclavian steal syndrome refers to a partial or complete occlusive lesion in the subclavian artery or brachiocephalic trunk at the origin of the vertebral artery. Due to the siphon effect (steal), blood flow in the ipsilateral vertebral artery reverses into the distal segment of the ipsilateral subclavian artery, leading to neurological symptoms of vertebrobasilar insufficiency and ischemic symptoms in the upper limb. It is more common in males than females, typically affecting individuals over 50 years old, with left-sided involvement being more frequent. Symptoms may include dizziness, limb paresis, and paresthesia.
Radiculitis
Radiculitis is an autoimmune peripheral neuritis characterized by demyelination of peripheral nerves and nerve roots, and infiltration of small vessels by inflammatory cells. Clinically, it often presents as muscle weakness and symmetrical paralysis. The most common form of radiculitis is acute inflammatory demyelinating polyneuropathy, also known as Guillain-Barré syndrome.
View detailsNervous migraine
Neuropathic migraine is primarily caused by headache or a feeling of heaviness in the head due to tension and contraction of the head muscles, often described as throbbing pain. It manifests as unilateral or bilateral pain, often accompanied by nausea and vomiting.
View detailsFugue
Fugue state, different from somnambulism. This condition often manifests as a sudden onset during the day or upon waking, where the patient wanders aimlessly for several hours or a day. They often regain consciousness abruptly, with amnesia or partial amnesia for the events that occurred during the episode.
View detailsAgnosia
Agnosia is an acquired disorder of perceptual function, characterized by the inability to correctly analyze and identify certain information from sensory pathways due to damage to specific areas in the cerebral hemispheres. This clinical symptom includes the loss of recognition abilities for visual, auditory, tactile, and body parts.
View detailsApraxia
Apraxia, also known as dyspraxia, is a disorder of higher brain function following brain damage. It is primarily characterized by the inability to properly plan and execute previously learned behaviors and actions, despite the absence of paralysis and deep sensory impairment (i.e., impaired sensation of position, movement, and vibration in joints and muscles).
View detailsMyotonic dystrophy
Myotonic dystrophy is an autosomal dominant inherited multi-system disorder characterized by progressive muscle weakness, muscle atrophy, and myotonia. The disease includes type 1, caused by variations in the myotonic dystrophy protein kinase gene (DMPK), and type 2, caused by variations in the cellular nucleic acid-binding protein gene (CNBP). Type 1 is the most common muscular dystrophy in adults, while type 2 is rare. Clinical manifestations mainly include skeletal muscle weakness, muscle atrophy or stiffness, cardiac conduction abnormalities, cataracts, and infertility.
