Introduction Due to the influence of the lesion, the stimulus must reach a strong degree to be perceived. Patients usually only perceive strong pain stimuli and warm stimuli. There is a period of incubation from the beginning of stimulation to perception. The nature and extent of stimuli and stimuli are often not correctly pointed out.

Cause

Thalamic pain appears on the opposite side of the lesion, more common in cerebrovascular diseases, such as cerebral hemorrhage, brain softening, etc., occasionally in the thalamic tumor and lesions near the thalamus, such as striatum tumors and vascular lesions.

Temperature sensation

Clinical manifestations:

Gently touching the limb of the patient immediately causes the severe pain that the limb is unbearable. The pain is not limited to the stimulating part, and can spread to the whole body. The intensity of the stimulus is not proportional to the susceptibility, which is an over-sensation phenomenon.

Differential diagnosis

Identification:

1. Feeling inversion: Feeling mistakes think cold feeling, non-painful stimulation induces pain and so on. Feeling inversion is rare in the clinic and is limited to shallow sensations.

2, feeling dull and known as feeling suppressed. The sensory threshold may be increased due to various factors or caused by emotional suppression. The patient does not perceive or feel mild to strong stimuli. Common in neurological diseases, delirium or other types of disturbances of consciousness, can also be found in schizophrenia, snoring and depression.

3, feeling allergic: refers to the sensory threshold is low, weak stimuli appear strong response to the sensory disorder. Allergies are common in superficial sensations, especially those with hyperalgesia, and tactile allergies are rare. Hyperalgesia can be caused by tactile or painful stimuli, and can also be caused by temperature stimulation.

4, feeling excessive: gently touch the limbs of the patient, immediately causing the pain of the side limbs unbearable, the pain is not limited to the stimulation site, can spread to the whole body, the intensity of this stimulus is not proportional to the sensitivity, that is Feeling excessive.
