Neuro Flashcards
Agraphesthesia
disorder of directional cutaneous kinesthesia or a disorientation of the skin’s sensation across its space. It is a difficulty recognizing a written number or letter traced on the skin after parietal damage.
Dysdiadochokinesia
DDK inability to perform rapid, alternating movements, such as flipping one’s hand from back to front on a flat surface, or screwing in a light bulb. DDK can cause problems with the upper and lower extremities as well as with speech.
Astereognosis
or tactile agnosia if only one hand is affected, is the inability to identify an object by active touch of the hands without other sensory input, such as visual or sensory information.
Dysarthria
motor speech disorder in which the muscles that are used to produce speech are damaged, paralyzed, or weakened. The person with dysarthria cannot control his or her tongue, larynx, vocal cords, and surrounding muscles, which makes it difficult for the person to form and pronounce words.
Hemineglect
also known as unilateral neglect, hemispatial neglect or spatial neglect, is a common and disabling condition following brain damage in which patients fail to be aware of items to one side of space
Cerebellum lesions are associated with (8):
DDK, ataxia, dysmetria, past-pointing, hypotonia, dysarthria, intention tremor, nystagmus
Which area of the brain generates a motor image in the absence of motion?
Premotor cortex
Virchow-Robin space separates:
perivascular space, separates wall of the blood vessel and pia mater
Absence seizure
An absence seizure causes you to blank out or stare into space for a few seconds. They can also be called petit mal seizures. Has spike and dome electroencephalogram.
Temporal lobe epilepsy
Temporal lobe epilepsy (TLE) is a chronic disorder of the nervous system characterized by recurrent, unprovoked focal seizures that originate in the temporal lobe of the brain and last about one or two minutes. TLE is the most common form of epilepsy with focal seizures.
Jacksonian seizure
Jacksonian seizure is a type of focal partial seizure, also known as a simple partial seizure. This means the seizure is caused by unusual electrical activity that affects only a small area of the brain. The person maintains awareness during the seizure. Jacksonian seizures are also known as a Jacksonian march.
Apoplectic seizure
The sudden loss of consciousness or control caused when a blood vessel in the brain ruptures or becomes blocked. When this happens, a person becomes apoplectic. This word also applies to someone who acts so upset, it is like he or she is having a stroke.
