Stroke and Cardiac Arrest
Other possible causes of short-term memory loss are stroke and cardiac arrest. Research suggests that the likelihood of cognitive decline, particularly in short-term memory, along with delayed and immediate recollection, increases with the duration of the cardiac arrest episode. Aside from short-term memory loss, executive function disorders and attention deficit disorders are two other typical neurological dysfunctions.
Short-term memory loss can happen due to cardiac arrest and stroke because these health conditions cause a lack of oxygen in the brain. A heart attack discontinues or greatly reduces the flow of blood that delivers oxygen to the heart. Due to the accumulation of fat and other things, the coronary arteries that carry blood to the cardiovascular system can become constricted. Once an artery ruptures, there will be blockage around it, which limits blood supply to the heart muscle.
To work normally, the brain requires a sufficient supply of oxygen. According to research, the brain cells start to decline once the oxygen level significantly reduces for several minutes or more. A lasting brain injury that could develop after a considerable amount of time is cerebral hypoxia. This brain injury is also commonly referred to as anoxic brain injury.
