The causes of brain ischemia vary from sickle cell anemia to congenital heart defects. Symptoms of brain ischemia can include unconsciousness, blindness, problems with coordination, and weakness in the body. Other effects that may result from brain ischemia are stroke, cardiorespiratory arrest, and irreversible brain damage.
[6] [7] Specific side effects of platinum compounds include hearing loss, tinnitus, and dysesthesia. These symptoms generally begin with the or third cycle of treatment and can last long after treatment completion. Indeed, the “coasting” phenomenon mentioned in the Symptoms section is a direct effect of platinum agents. Of the platinum ...
Ischemia is a vascular disease involving an interruption in the arterial blood supply to a tissue, organ, or extremity that, if untreated, can lead to tissue death. It can be caused by embolism, thrombosis of an atherosclerotic artery, or trauma. Venous problems like venous outflow obstruction and low-flow states can cause acute arterial ischemia.
The most common cause of a subarachnoid hemorrhage is an aneurysm rupture due to the weakened blood vessel walls and increased wall stress. [48] The neurologic symptoms are produced by the blood mass effect on neural structures, from the toxic effects of blood on the brain tissue, or by the increasing of intracranial pressure. [49]
Hemorrhage into the basal ganglia or thalamus causes contralateral hemiplegia due to damage to the internal capsule. [7] Other possible symptoms include gaze palsies or hemisensory loss. [7] Intracerebral hemorrhage into the cerebellum may cause ataxia, vertigo, incoordination of limbs and vomiting. [7]
A surgical nerve decompression can relieve pressure on the nerve but cannot always reverse the physiological changes that occurred before treatment. Nerve injury by a single episode of physical trauma is in one sense an acute compression neuropathy but is not usually included under this heading, as chronic compression takes a unique ...
[7] [8] Treatments for spinal cord stroke are mainly determined by the symptoms and the causes of the disease. For example, antiplatelet and corticosteroids might be used to reduce the risk of blood clots in ischaemic spinal stroke patients, while rapid surgical decompression is applied to minimize neurological injuries in haemorrhagic spinal ...
The ischemic (ischaemic) cascade is a series of biochemical reactions that are initiated in the brain and other aerobic tissues after seconds to minutes of ischemia (inadequate blood supply). [1] This is typically secondary to stroke , injury, or cardiac arrest due to heart attack .
