Answer:
Altered states of consciousness
Explanation:
In health and medicine, an altered state of consciousness is defined as any state of awareness that significantly differs from a regular waking awareness state (without actually being unconscious). In other words it refers to a significant deviation from a regular waking awareness state.
When someone has a stroke or any other form of brain damage, they experience low levels of awareness that significantly differ from the regular waking awareness state, therefore, this would be an example of altered states of consciousness.
