What is neglect?

summary

Neglect refers to the obvious inattention or disturbance of perceptual response to objects in one's own body or field of vision, which is called neglect. In both cases, there is a tilt of attention and orientation, which involves different types of sensory, motor and memory patterns, causing a series of clinical manifestations. What is neglect? Let's talk about it

What is neglect?

Patients usually use only one right hand to do things and gesture, while the other left hand seems to be forgotten and left idle; When walking, the affected arm does not swing or rarely swings, just like the patients with hemiparkinsonism; When the affected arm is in a very uncomfortable position, it also remains motionless for a long time. When walking, the affected side often collides with obstacles; Put a pair of shoes in front of the patient. The patient only wears the one on the healthy side and ignores the one on the affected side.

If the patients are required to open and clench their fists at the same time for 20 consecutive times, the normal people can do bilateral repetitive movements at the same time without mistakes, while the patients do it continuously on one side and do not do it on the other side or miss it obviously; When the stimulation ignores the side limb, whether it is needling, pinching, pinching the skin or flexing the ring finger, the patient will say pain, but does not retract the hand; It is suggested that patients are not impaired in perception of noxious stimuli, but in response to noxious stimuli, which is a common and valuable sign in motor neglect.

Sensory neglect, also known as unilateral inattention, is usually manifested in the form of sensory extinction. It can be somatosensory, visual or auditory. The patient can't Orient, respond or report to the stimulation from the lesion side; The lesion did not damage sensory afferent pathway, primary sensory cortex or thalamic sensory nucleus.
