Apraxia
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.
View detailsRadial nerve palsy
The radial nerve is the main nerve of the posterior cord of the brachial plexus, controlling sensation and movement in the arm and hand, as well as extension of the elbow, wrist, and fingers. Radial nerve palsy is a condition that occurs after the radial nerve is damaged by external factors, leading to muscle weakness, numbness, or even complete paralysis in the shoulder, armpit, arm, and fingers. It typically manifests as numbness and weakness in the muscles from the triceps brachii in the arm to the fingers, with the wrist drooping and an inability to lift it voluntarily.
Diffuse sclerosis
Schilder's disease is a rare, sporadic demyelinating disease primarily seen in children. It was first reported by Schilder in 1912 as diffuse periaxial encephalitis, also known as diffuse periaxial encephalomyelitis or Schilder's disease. It can cause cognitive impairment, aphasia, headache, hemiplegia, and other symptoms.
View detailsFacial hemiatrophy
Facial muscle atrophy refers to a condition characterized by dystrophy of the facial striated muscles, leading to a reduction in muscle volume, thinning, or even disappearance of muscle fibers. It is more common in middle-aged women and often presents as involuntary twitching of muscles on one side of the face, gradually extending to the other side, accompanied by numbness and twitching at the corner of the mouth.
View detailsPeripheral neuritis
Peripheral neuritis refers to the damage of nerves at the ends of limbs due to various reasons, leading to corresponding symptoms, such as those affecting motor nerves, sensory nerves, and autonomic nerves. The prevalence of peripheral neuritis is approximately 2% to 7%, with the elderly being more susceptible.
View detailsLeukomalacia
Periventricular leukomalacia (PVL) is a common secondary brain injury in premature infants. It frequently occurs in premature infants between 23 and 32 weeks of gestation, primarily manifesting as motor impairments (mainly spastic diplegia and quadriplegia), intellectual disability, seizures, and ocular abnormalities such as strabismus, nystagmus, and decreased vision.
View detailsCerebral artery occlusion
Cerebral artery occlusion primarily refers to pathological changes in the cerebral arteries, leading to slow blood flow and increased blood viscosity, ultimately resulting in cerebral artery occlusion. This condition mainly affects the elderly, with women having a lower incidence rate than men.
View detailsCerebral steal syndrome
Cerebral artery steal syndrome refers to a condition where, due to arterial stenosis or occlusion caused by various reasons, the pressure in the distal artery significantly decreases. This leads to a siphon effect, causing blood from an adjacent artery to flow retrogradely into the lower-pressure artery to compensate for its blood supply. Consequently, the blood supply to the "stolen" cerebral artery is significantly reduced, leading to cerebral ischemia and the appearance of clinical symptoms or signs. This condition is common in individuals with atherosclerosis and dyslipidemia.
