Anoxic brain injury occurs when the brain is deprived of oxygen for a significant period. This lack of oxygen can result from various situations, such as drowning, cardiac arrest, or suffocation. The brain cells begin to die within minutes without oxygen, leading to potential long-term damage or disability. Symptoms of anoxic brain injury can vary widely, depending on the severity and duration of the oxygen deprivation. Common effects include cognitive impairments, memory loss, and difficulties with motor skills. Early intervention and rehabilitation are crucial for improving outcomes and helping individuals regain lost functions.
