CONSCIOUSNESS INTRODUCTION Consists of perceptions, thoughts and feelings. The phenomenon of consciousness is still unclear and has a meaning and a different perspective. DEFINITION. Consciousness: The ability of being awake and aware of one’s sorroundings. Unconscious: - Not conscious.

An altered state of consciousness is any mental state induced by physiological, psychological, or pharmacological maneuvers or agents, which deviates from the normal waking state of consciousness TYPES OF ALTERED CONSCIOUSNESS. ACCIDENTAL AND PATHOLOGICAL CAUSES Traumatic experience Defined as a lesion caused by an external force Examples include impact to the brain caused by blunt force (i.e., a car accident). The reason a traumatic experience causes altered states of consciousness is because it changes how the brain works. Epilepsy epilepsy can be described as a brain disorder that causes seizures. During the seizure it is said that the patient will experience loss of mental control Oxygen deficiency oxygen deficiency impacts the brain Study confirmed that inhaling substances other than oxygen results in impaired self-awareness Infections A prime example of an infection includes meningitis. Meningitis is an infection that causes the coverings of the brain to swell. Psychosis Another pathological cause is psychosis, otherwise known as a psychotic episode.

This stage is also known as the alpha wave stage. b) Second stage: Still known as alpha wave stage. In this stage the individual is already in deep sleep and difficult to be awakened. c) Third stage: This stage consists of the beta waves. Additional physiological changes occur. In this stage it is difficult to awaken the individuals by natural stimuli such as noise and light. d) Forth stage: This stage consists of the delta wave. It's also hard to awaken individuals who are in this stage. This stage will become short when age increases. e) Fifth stage: Dreams occur during this stage. This stage is used in many psychological studies Consists of delta waves. Mental changes occur in this stage. This stage is known as rapid eye movement stage.
