PRIVATE SYMPTOMATOLOGY OF SENSITIVITY DISORDERS
The lesion of the peripheral nerve trunk causes a violation of all types of sensitivity in the zone of its innervation, i.e., in the peripheral mononeuritic type.
The damage to the plexus (cervical, brachial, lumbar, sacral) causes sensory, motor and autonomic disorders in the region innervated by the nerves, combined with pain and paresthesias and belong to the peripheral type.
The defeat of the posterior roots appears acute radicular pain.
The lesion of the posterior horn of the spinal cord is characterized by a segmental dissociated type of sensitivity disorder. Tendon and periosteal reflexes are lost or reduced, dull, diffuse, poorly localized pain is noted.
The defeat of the white front adhesion is similar to the defeat of the horn
The defeat of the posterior cord of the patient loses an idea about the position of parts of his body in space, about the direction and range of movements, which is manifested by impaired coordination of movements, for example, with funicular myelosis, dorsal toe.
The defeat of the lateral cord causes disorders of pain and temperature sensitivity of the conductor type on the opposite side to the hearth
The transverse lesion of half of the spinal cord is accompanied by Brown-Sekar syndrome (.29) - central paralysis from the bottom of the lesion level and a violation of the musculoskeletal feeling on the affected side.
The defeat of the thalamus causes a “trigemi syndrome” - henanesthesia of pain, temperature and tactile sensitivity, sensitive hemiaxia (loss of joint and muscular feeling on the opposite side) and hemianopsia of opposite visual fields.
The lesion of the inner capsule also causes hemianesthesia, hemiaxia and hemianopia on the opposite side.
Damage to the sensitive area of the cerebral cortex (postcentral gyrus) leads to loss of all types of hemithip sensitivity on the opposite side. In fact, loss of sensitivity in monotype (on the arm, leg, face, etc.) is more common than in hemitype, since not all postcentral gyrus is usually affected, but only its individual sections. So, with the defeat of its upper portion, anesthesia or hypesthesia of the foot (less often the entire leg) is detected, the lower portion — the face, the tongue on the side opposite to the outbreak.
NI Grashchenkov allocates five degrees of impaired consciousness.
Grade I — the patient is poorly oriented in the environment, does not adequately assess the situation, but can be answered quite specifically to the questions posed.
Grade II — the patient does not understand the question, but independently pronounces individual words or phrases, experiencing what happened.
Grade III — the patient does not answer questions and does not spontaneously say anything, but verbal answers occur when pain is applied to the stimulation.
With these disturbances of consciousness, more or less disorder of the cortical functions of the analyzer occurs. If the answers occur only to painful irritation, then this indicates the safety of the functions of the thalamus.
In the fourth degree of loss of consciousness, the upper stem level is also turned off, only the function of the medulla oblongata is maintained.
The patient saved only breathing, no reactions to the surrounding there.
V degree of impairment of consciousness combined with disorders of the heart and respiratory activity. This is often a pre-diagonal condition, which indicates a violation of the centers of the medulla oblongata. This is the worst degree of dysfunction of the medulla.
Grades I, II and III of cerebral disorder are not a contraindication to surgery.
As for the IV and especially the V degree of impaired consciousness, they are a direct contraindication to surgical procedures. To assess the severity of the impaired brain activity, the depths of loss of consciousness check the reduction or absence of pupillary, corneal and pharyngeal reflexes. The absence of these reflexes of evidence
Epidural hematoma occurs between the dura mater and the bones of the skull. The blood comes from damaged veins located on the outer surface of the dura mater. It is characteristic that after an injury an unconscious state occurs and other signs of concussion of the brain can be detected, then the consciousness becomes clear, a bright period appears, during which the patient feels more or less satisfactory. The light period lasts several hours, and in rare cases even one or two days. The development of monoparesis is among the early and almost permanent signs of epidural hematoma. Most often observed paresis of the upper limb. Sometimes hemiparesis develops, but with a predominance of damage to one limb.
The cerebrospinal fluid is colorless or slightly amber-yellow in color, but red blood cells are usually absent. On the side of the epidural hematoma, pupil dilation is noted. Sometimes stagnant discs are found.
Subdural hematoma is formed between the hard and spider shells, bleeding occurs as a result of rupture or tearing of the cerebral veins, which flow into the sinuses at the site of their exit beyond the limits of the arachnoid membrane, resulting in a platelet
These hematomas are located above the arachnoid membrane. Usually in such hematomas, blood coagulation does not occur. They slowly increase in size and begin to squeeze the brain, causing it to shift, often with wedging of the medulla oblongata into the large foramen, which in the absence of timely surgical intervention leads to death. Meningeal syndrome is found in almost all cases of subdural hematomas. Subdural hematoma usually occurs within a few hours, and sometimes even a day after the injury. Cerebral phenomena caused by trauma, pass, the patient starts to work and suddenly there is a headache, vomiting, bradycardia, drowsiness, anisocoria.
With subarachnoid hemorrhage there is no bright gap, the patient experiences an acute headache called “dagger”, psychomotor agitation appears, meningeal phenomena quickly increase; cerebrospinal fluid - “the color of meat mud”, contains a large number of fresh and leached red blood cells.
Clinical manifestations of parenchymal and intraventricular hemorrhage resemble strokes.

- PRIVATE SYMPTOMATOLOGY OF SENSITIVITY DISORDERS
The lesion of the peripheral nerve trunk causes a violation of all types of sensitivity in the zone of its innervation, i.e., in the peripheral mononeuritic type. This results from the fact that in a trunk of a nerve pass nerve fibers for various types of sensitivity. The damage of individual nerve fibers can be more or less deep, which leads to unequal violation of certain types
- Cortical Disorder
(Internet) Sensitivity - the body's ability to perceive irritation emanating from the environment or from its own organs and tissues. In physiology, the entire set of afferent systems is united by the concept of reception. Sensitivity is a special case of reception when afferent impulses lead to the formation of sensations. Not everything that is subject to reception is felt. For example:
- TYPES OF DISTURBANCE OF SENSITIVITY
- TYPES OF DISTURBANCE OF SENSITIVITY
- Sensitivity and types of sensitivity disorders
Sensitivity - the body's ability to perceive irritation emanating from the environment or from its own tissues and organs. The analyzer consists of three sections: the receptor, the conductor part and the cortical department. Receptors are the terminal formations of sensory nerve fibers that perceive changes in the body or outside of it and transmit it in the form of impulses.
- Symptomatology of skin rashes
Roseola - a speck of pink, red, purple-red or purple in size up to 5 mm. Roseola shape is round or irregular; edges are clear or blurry; above the skin does not protrude, disappears when pressed on the skin, when released, reappears. Multiple roseola 1-2 mm in size - petechial rash. Stain - the color is the same as that of roseola, but the size is from 5 to 20 mm, not
- MENTAL DISORDERS (PR) AND DISORDERS OF BEHAVIOR (RP), THEIR MEDICAL AND SOCIAL SIGNIFICANCE
Class V (ICD-10), encrypted - F 00 - F 99. Mental health (mental health) is a dynamic process of mental activity characterized by the determination of mental phenomena, the harmonic relationship between the reflection of reality circumstances and the attitude of the individual to it, the adequacy of the body’s response to social, psychological and physical (including biological)

- SENSITIVITY RESTORATION
When reading this section, one should take into account the fact that we are talking about the possibility of restoring sensitivity, and not its normalization. With anatomical damage to the spinal cord, recovery of sensitivity proceeds in a certain sequence. The surface skin sensitivity is restored first. Gradually emerging foci of skin sensitivity expand and
The primary perception of all the stimuli in the human body is carried out by receptors - specific cells that perceive the effects of external and changes in the internal environment of the body. Exteroreceptor Receptors Proprioceptors Interoreceptors General features of three-neural pathways of superficial and deep sensitivity • The first neuron is located in the intervertebral node.
- RESEARCH SENSITIVITY
In the study of sensitivity based on the testimony of patients in response to certain stimuli. However, the study of sensitivity in children presents great difficulties, since the child cannot always clearly differentiate the stimulation, correctly analyze his feelings and adequately describe them. In young children, it is often necessary to confine ourselves to researching only
