The emergence and activity of pathological determinants

Determinant may combine CNS pathological structures in the system and determine the nature of the activity of these structures. If the regulation is weakened structures that perceive impulses from the neuron determinants, the determinant of subjects them to its effects.

In the early stages of development of nervous disorders pathological determinant activated by specific stimuli, ie, irritations, which are adequate for the formation of the central nervous system, which became the determinant (eg, light stimuli, if the determinant is education in the visual analyzer system, pain - if there was a determinant in the system sensitivity to pain and so on.). This rule also applies to disorders of higher nervous activity, neurotic reactions: their determinant relief activated by the action of the stimuli that led to its formation (for example, the same conflict neurotic situation and so on.). These features determine the specificity of provoking actions that cause bouts of nervous disorders.

In the later stages of the determinant can be activated by stimuli of different nature, in connection with which attacks can be triggered by different influences. Furthermore, pathological determinant may be activated accidentally due to spontaneous activation of the generator.

CNS experiencing long-term effects of pathological determinants over time may themselves become determinants. First, such a secondary determinant is dependent on the primary: it disappears when liquidated the primary determinant. In the future, the secondary determinant may acquire an independent pathogenetic significance. Sometimes secondary determinant is stronger than the original, and becomes the leader. The establishment of primary and secondary determinants is essential for the understanding of the pathogenic features of nervous disorders and their proper diagnosis and pathogenetic therapy.

Pathological determinant is the most resistant part of the pathological system. During the suppression of the pathological system or its natural elimination determinant structure is retained even when other education system has returned to normal and went out of its composition ( "determinant of the last to die"). When you restore a pathological system under the influence of new actions before the other activated determinant structure ("determinant resurrected first").
