Difference between Altered level of consciousness and Brain herniation

Altered level of consciousness vs. Brain herniation

An altered level of consciousness is any measure of arousal other than normal. Brain herniation is a potentially deadly side effect of very high pressure within the skull that occurs when a part of the brain is squeezed across structures within the skull.

Abnormal posturing

Abnormal posturing is an involuntary flexion or extension of the arms and legs, indicating severe brain injury.

Brainstem

The brainstem (or brain stem) is the posterior part of the brain, adjoining and structurally continuous with the spinal cord.

Cerebellar tentorium

The cerebellar tentorium or tentorium cerebelli (Latin: "tent of the cerebellum", Greek: "Σκηνίδιο της παρεγκεφαλίδας") is an extension of the dura mater that separates the cerebellum from the inferior portion of the occipital lobes.

Cerebral cortex

The cerebral cortex is the largest region of the cerebrum in the mammalian brain and plays a key role in memory, attention, perception, cognition, awareness, thought, language, and consciousness.

Cerebral hemisphere

The vertebrate cerebrum (brain) is formed by two cerebral hemispheres that are separated by a groove, the longitudinal fissure.

Coma

Coma is a state of unconsciousness in which a person cannot be awaken; fails to respond normally to painful stimuli, light, or sound; lacks a normal wake-sleep cycle; and does not initiate voluntary actions.

Glasgow Coma Scale

The Glasgow coma scale (GCS) is a neurological scale which aims to give a reliable and objective way of recording the conscious state of a person for initial as well as subsequent assessment.

Midbrain

The midbrain or mesencephalon (from Greek mesos 'middle', and enkephalos 'brain') is a portion of the central nervous system associated with vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation.
