Spastic cerebral palsy is the type of cerebral palsy characterized by spasticity or high muscle tone often resulting in stiff, jerky movements. [110] Itself an umbrella term encompassing spastic hemiplegia , spastic diplegia , spastic quadriplegia and – where solely one limb or one specific area of the body is affected – spastic monoplegia.
This will narrow the possible causes. If the cause of the hypotonia is found to lie in the brain, then it can be classified as a cerebral palsy. If the cause is localized to the muscles, it can be classified as a muscular dystrophy. If the cause is thought to be in the nerves, it is called hypotonia due to polyneuropathy.
Ataxic cerebral palsy is known to decrease muscle tone. [3] The most common manifestation of ataxic cerebral palsy is intention (action) tremor, which is especially apparent when carrying out precise movements, such as tying shoe laces or writing with a pencil. This symptom gets progressively worse as the movement persists, causing the hand to ...
Athetoid cerebral palsy, or dyskinetic cerebral palsy (sometimes abbreviated ADCP), is a type of cerebral palsy primarily associated with damage, like other forms of CP, to the basal ganglia in the form of lesions that occur during brain development due to bilirubin encephalopathy and hypoxic–ischemic brain injury. [1]
Possible causes of ataxias may include stroke, tumor, infection, trauma, or degenerative changes in the cerebellum. These types of hyperkinetic movements can be further classified into two groups. The first group, hereditary ataxias, affect the cerebellum and spinal cord and are passed from one generation to the next through a defective gene.
altered muscle tone (hypotonia or hypertonia) – a decrease or increase in the baseline level of muscle activity; decreased endurance; exaggerated deep tendon reflexes including spasticity, and clonus (a series of involuntary rapid muscle contractions) Such signs are collectively termed the "upper motor neuron syndrome".
There is no known cause of Bell’s palsy, though it's often linked to viral infections, including viruses such as herpes zoster (which causes chicken pox and shingles) and herpes simplex (which ...
Many conditions that cause paraplegia or quadriplegia begin as monoplegia. Thus, the diagnosis of spinal paraplegia must also be consulted. In addition, multiple cerebral disorders that cause hemiplegia may begin as monoplegia. [1] Monoplegia is also frequently associated with, and considered to be the mildest form of, cerebral palsy.
