1. Coma

   A coma is a deep state of prolonged unconsciousness in which a person cannot be awakened, fails to respond normally to painful stimuli, light, or sound, lacks a normal wake-sleep cycle and does not initiate voluntary actions. Coma patients exhibit a complete absence of wakefulness and are unable to consciously feel, speak or move. Comas can be derived by natural causes, or can be medically induced.Clinically, a coma can be defined as the inability consistently to follow a one-step command. It can also be defined as a score of ≤ 8 on the Glasgow Coma Scale (GCS) lasting ≥ 6 hours. For a patient to maintain consciousness, the components of wakefulness and awareness must be maintained. Wakefulness describes the quantitative degree of consciousness, whereas awareness relates to the qualitative aspects of the functions mediated by the cortex, including cognitive abilities such as attention, sensory perception, explicit memory, language, the execution of tasks, temporal and spatial orientation and reality judgment. From a neurological perspective, consciousness is maintained by the activation of the cerebral cortex—the gray matter that forms the outer layer of the brain—and by the reticular activating system (RAS), a structure located within the brainstem.

1. Coma

   In medicine, a coma is a state of unconsciousness lasting more than six hours, in which a person: cannot be awakened; fails to respond normally to painful stimuli, light, or sound; lacks a normal sleep-wake cycle; and, does not initiate voluntary actions. A person in a state of coma is described as being comatose. Although a coma patient may appear to be awake, they are unable to consciously feel, speak, hear, or move. For a patient to maintain consciousness, two important neurological components must function impeccably. The first is the cerebral cortex which is the gray matter covering the outer layer of the brain. The other is a structure located in the brainstem, called reticular activating system. Injury to either or both of these components is sufficient to cause a patient to experience a coma. The cerebral cortex is a group of tight, dense, "gray matter" composed of the nucleus of the neurons whose axons then form the "white matter", and is responsible for perception, relay of the sensory input via the thalamic pathway, and most importantly directly or indirectly in charge of all the neurological functions, from simple reflexes to complex thinking.

Examples of COMA in a Sentence

1. Ryan Newman:

   I was medically treated to not know( about my condition.) They were trying to keep me in a somewhat of a medically-induced coma from what I've been told, and that medicine kind of zoned me out, so I really don't have any memories or recollection of any of my crash until I actually had my arms around my daughters walking out of the hospital.

2. Mohammed Allan:

   Mohammed Allan is very, very weak, he is out of the induced coma and he has spoken to his lawyers, and his demands remain the same.

5. Anna Zafesova:

   He has dozens of young women and men perfectly capable of carrying on his investigative work. Maybe they are less charismatic than he, but they are proof that the Russian opposition is not only virtual and cannot be silenced with the poisoning of its leader. POISONED KREMLIN CRITIC ALEXEI NAVALNY OUT OF COMA AND RESPONSIVE: GERMAN HOSPITAL Navalnys spokeswoman Kira Yarmysh and fellow team member Georgi Alburov front the Tatarstan film, and said they were followed and harassed while shooting by men who blocked their paths with quad bikes or lurked nearby. Some dramatic images along those lines appear in the film.Yarmysh talks about how Tatarstan was supposed to be one of Navalnys stops on his late summer swing through Russian regions ahead of elections. Navalny was lobbying forSmart Voting. He argued that ifhe and people like him couldnt run in elections in Russia, the next best thing wasto simply vote for a candidate who is not from the same party as President Vladimir Putin, United Russia. Navalnyfamously called it the party of crooks and thieves and wantedto chip away at its monopoly on power howeverpossible.He believes Smart Voting can eventually dislodge it from power. GERMANY SUGGESTS HALT TO RUSSIA PIPELINE PROJECT, SEEKS COOPERATION WITH NAVALNY POISONING INVESTIGATION In the documentary from Kazan, the capital of Tatarstan, Navalnys team keeps up his stylistic pace with drone video of what itidentifiesas the palatial homes of the regional president and his family, punctuated withvideoof the vast collection of fancy watches from Patek Phillipe to Breguet worn byleaderRustam Minnikhanov. Even if you dont understand Russian, it is compelling TV, Zafesova said. Navalnys investigations have evolved over the years from merely facts and analysis on his blog to full-scale movies.He invented a whole new way to oppose power, a mix of media and politics which is very important in a censored media environment like Russia and fills the void of free media as well as free debate and an independent judicial system.Navalnys videos are funny, clever, precise and shocking, not just angry denunciations of the wrongdoings of government.
