Childhood muscular dystrophy
Muscular dystrophy refers to a group of diseases characterized by chronic, progressive muscle weakness and atrophy. Most types of muscular dystrophy present with symptoms in childhood or adolescence, such as frequent falls, muscle weakness, muscle cramps, and difficulty standing up, climbing stairs, running, or jumping.
View detailsIdiopathic inflammatory myopathy
Idiopathic inflammatory myopathy is a subacute or chronic inflammatory myopathy characterized by muscle fiber necrosis, regeneration, and inflammatory cell infiltration in the interstitial tissue. The peak incidence in children is between 10 and 14 years old, and in adults, it is between 45 and 54 years old. The average age of onset in males is greater than in females, but the incidence in females is significantly higher than in males. The main symptoms are weakness and pain in the proximal limbs, neck, and pharyngeal muscles, which can manifest as difficulty raising the arms, inability to lift the legs, and inability to stand up after squatting.

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.
Sleep-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.

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.
View detailsRadiculitis
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.
