Spatial perception disorder

Introduction Spatial perception barrier refers to the perceived comprehensive obstacle to the size ratio of things, such as the spatial structure. For example, the image of the object is much larger than the actual object, and it is called the visually significant disease; it is much smaller than the actual object, and it is called the visually ill; The face is deformed, the nose is skewed, or the shape of the cabinet is changed. It is called visual distortion. If you look at the distant object or look at the distant object, it is called the empty sheep or the visual dislocation. . The above various spatial perception comprehensive obstacles are more common in itching and schizophrenia.

Cause

1. The brain is struck by trauma, and intracranial hypertension causes damage to brain cells.

2, epilepsy, schizophrenia and so on.

Collect detailed medical history of the patient and find that patients with spatial symptoms can be guessed if they have the following symptoms. The image of the object is much larger than the actual object. It is called visually significant, much smaller than the actual object. The face of a person is deformed, the nose is skewed, or the shape of the cabinet is changed. It is called visual distortion; if the far object is seen very close or the near object is far away, it is called the empty distance sheep or the dislocation. disease. EEG and brain CT are required.

Differential diagnosis

Spatial perception impairments need to be differentiated from the symptoms below.

(1) Temporal lobe epilepsy: clinically common visual objects become larger, visual objects become smaller, and visual objects are deformed. This kind of perceptual change usually occurs in the onset of the disease, or it may be a precursor to an episode. The patient feels that the object being viewed becomes larger, sometimes smaller, sometimes farther away, and sometimes close, and more complex when there is a visual distortion. The above performance often affects the behavior of the patient.

(2) Schizophrenia: There may be a real disintegration, which is a manifestation of a comprehensive barrier to spatial perception. The patient's feelings about the attributes of the outside world have not changed, but the impression of the external things is not vivid, not obvious, often unclear, such as barriers, illusory, lack of realism.

(3) Epidemic encephalitis B: In its acute phase, hyperthermia can be above 40 °C, there may be varying degrees of disturbance of consciousness or even coma, resulting in mental symptoms, which may appear larger and visually variable. Small, visual distortions and other perceptual comprehensive obstacles. As the disturbance of consciousness improves, the perception barrier can quickly disappear.
