Classification and differential diagnosis of impaired consciousness

Consciousness disorder refers to a pathological process that cannot correctly understand its own state and/or objective environment and cannot respond correctly to environmental stimuli, and its pathological basis is the
dysfunction of the cerebral cortex, thalamus and brainstem reticular system.

So how do neurology, neurosurgery, and neurology recognize consciousness disorders?

Moderate impaired consciousness

coma

It is one of the most serious disorders of
consciousness.
The patient is completely unconscious, various strong stimuli can not wake him up, there is no purposeful activity, and he cannot open his eyes
spontaneously.

The causes of consciousness disorders are diverse, involving multiple disciplines and systems, and should be expanded when receiving such patients, and preconceptions should not be avoided; The patient's history and accompanying symptoms should be carefully examined, and a thorough physical examination and early laboratory tests should be performed to determine the cause to avoid misdiagnosis or delay in treatment
