An impairment of brain function caused by injury to the head. The speed and degree of recovery depend on the severity of the brain injury. symptoms may include headache, disorientation, paralysis, and unconsciousness.
A brief loss of consciousness owing to a head injury; often followed by temporarily disturbed vision and loss of memory.
A severe impact to the skull causing rupturing of small blood vessels in the brain.
The act of applying force to any part of the body.
Loss of consciousness for a short period, caused by a blow to the head.
Violent Jarring or shaking, as from a severe blow or shock, esp. one to the head. A concussion may cause a limited period of unconsciousness.
Brain trauma resulting in transient and/or immediate loss of consciousness due to injury to the soft structure of the brain.
A brief loss of consciousness following a head injury. The length of time the person is unconscious may relate to the severity of the concussion. A concussion may be accompanied by headache, faintness, nausea or vomiting, slightly blurred vision, and difficulty concentrating.
A limited period of unconsciousness caused by injury to the head. It may last for a few seconds or a few hours. There is no recognizable structural damage to the brain, although repeated concussion eventually causes symptoms suggesting brain damage.
An injury resulting from impact with an object.
A short loss of consciousness following a severe bump to the head, during which the soft brain tissue comes into contact with the skull.
A brain injury refers to damage inflicted upon the brain, resulting in a sudden and transient disruption of normal brain function. This type of injury typically leads to a temporary impairment of various cognitive, sensory, or motor functions. Common examples of brain injuries include concussions, which are often caused by a forceful impact to the head. Such injuries can result in a range of symptoms, including dizziness, confusion, memory problems, and difficulties with coordination. While the effects of a brain injury may be temporary, it is crucial to seek medical attention and proper management to ensure a full recovery and minimize any potential long-term consequences.
A transient state of unconsciousness, often resulting from a forceful impact to the head, characterizes a concussion. This loss of consciousness arises from a brief disruption in the electrical activity within the brain. Typical symptoms experienced after a concussion include confusion, difficulty recollecting recent events leading up to the injury, dizziness, blurred vision, and vomiting.
It is crucial for anyone who has experienced a concussion, regardless of its duration, to seek immediate medical attention. Prompt medical assessment is essential in cases where persistent symptoms persist or new symptoms arise, such as drowsiness, breathing difficulties, recurring vomiting, or visual disturbances. These signs could indicate brain damage or an extradural hemorrhage, and medical advice should be promptly sought. Furthermore, repeated concussions have the potential to result in a condition known as punch-drunk syndrome.
Following a blow on the skull, the brain may be so rocked about that concussion results. It may last a few minutes or days, and the first sign of recovery is often an attack of vomiting. On becoming conscious the casualty may suffer from loss of memory and be unable to recall either the blow or how he arrived in his present position. Following recovery he may suffer with postconcussional headaches, which may persist for many months; in severe cases there may follow a change of personality— a happy man becoming quiet and moody. However, if the only brain damage is concussion and a general shaking-up, the patient gradually recovers. If there has been more severe damage, such as bleeding into the skull or brain laceration, blood collects and presses on the brain, producing cerebral compression. Concussion may pass into compression without the casualty regaining consciousness, and sometimes he may come around from concussion and then slip into coma from the late onset of compression. The concussion case is quiet and appears to be just deeply asleep, but when compression sets in the whole picture changes. The patient becomes deeply unconscious, red-faced, breathes noisily, and has a slow, bounding pulse. The pupils of his eyes may be unequal or widely dilated and not react to light. If, however, the bleeding has been only slight and stops spontaneously the casualty may show none of these signs, and since some people are born with unequal pupils this sign can sometimes be misleading. In either case the patient should be kept at rest in a propped-up sitting position, dentures should be removed, and medical aid should be summoned.
