Diseases of the nervous system (neurology)

Cryptococcal meningitis

Cryptococcal meningitis develops when the encapsulated yeast Cryptococcus neoformans, which belongs to human opportunistic pathogens, is affected.

Aplasia of the corpus callosum

A malformation in the form of a complete or almost complete absence of adhesion of nerve fibers connecting the hemispheres of the brain is defined as aplasia of the corpus callosum, which is synonymous with its agenesis, that is, its lack of development during development.


Disorder of the functions of the olfactory system, which manifests itself in the fact that ordinary smells seem unpleasant and even disgusting to a person, is defined as parosmia, troposmia or cacosmia (literally from Greek - a bad smell).


The term "meningism" is a syndrome that occurs in some common infectious pathologies under the influence of irritation of the meninges. Meningism is characterized by such signs as headache, stiffness of the cervical muscles, an increase in intracranial pressure against the background of an unchanged composition of cerebrospinal fluid.

Idiopathic generalized and focal epilepsy

A systematic review and meta-analysis of studies worldwide showed that the point prevalence of active epilepsy was 6.38 per 1000 people, and the lifetime prevalence was 7.6 per 1000 people.

Causalgia: what is this disease?

The list of definitions can be continued, but here is a special medical term - causalgia - which means severe prolonged pains of a burning character.

Lissencephaly of the brain

Among organic cerebral pathologies, such a congenital anomaly in the development of the brain as lissencephaly stands out, the essence of which lies in the almost smooth surface of the cortex of its hemispheres - with an insufficient number of convolutions and grooves.

Hypotension syndrome in children and adults

A decrease in skeletal muscle tone (residual tension and muscle resistance to passive stretching) with a deterioration in its contractile function is defined as muscle hypotonia.

Spinal shock in humans

In neurology, spinal or spinal shock is defined as a clinical syndrome arising from an initial neurological response to traumatic spinal cord injury - with a reversible loss or reduction of all of its functions below the level of the injury.

Charcot-Marie-Tooth disease

Peroneal muscle atrophy, syndrome or Charcot-Marie-Tooth disease is a whole group of chronic hereditary diseases with damage to peripheral nerves.
