 Other and ill-defined cerebrovascular disease- 437 is a non-specific code that cannot be used to specify a diagnosis
Cerebral atherosclerosis- 437.0 is a specific code that can be used to specify a diagnosis
- 437.0 contains 27 index entries
Other generalized ischemic cerebrovascular disease- 437.1 is a specific code that can be used to specify a diagnosis
- 437.1 contains 11 index entries
Hypertensive encephalopathy- Brain dysfunction or damage resulting from sustained MALIGNANT HYPERTENSION. When BLOOD PRESSURE exceeds the limits of cerebral autoregulation, cerebral blood flow is impaired (BRAIN ISCHEMIA). Clinical manifestations include HEADACHE; NAUSEA; VOMITING; SEIZURES; altered mental status (in some cases progressing to COMA); PAPILLEDEMA; and RETINAL HEMORRHAGE.
- 437.2 is a specific code that can be used to specify a diagnosis
- 437.2 contains 6 index entries
Cerebral aneurysm nonruptured- 437.3 is a specific code that can be used to specify a diagnosis
- 437.3 contains 12 index entries
Cerebral arteritis- 437.4 is a specific code that can be used to specify a diagnosis
- 437.4 contains 4 index entries
Moyamoya disease- A chronic cerebral vasculopathy primarily occurring in childhood and characterized by slowly progressive carotid artery narrowing and occlusion at the base of the brain. An extensive network of anastomoses forms between branches of the carotid arteries, resulting in a characteristic angiographic appearance. The condition may be idiopathic (classic moyamoya disease) or occur in association with ANEMIA, SICKLE CELL; DOWN SYNDROME; CRANIOCEREBRAL TRAUMA; RADIOTHERAPY induced arterial injury; NEUROFIBROMATOSIS; and other diseases. Clinical manifestations include hemiparesis, headache, seizures, and delayed mental development. In older individuals, this disease may present as SUBARACHNOID HEMORRHAGE. (From Adams et al., Principles of Neurology, 6th ed, p831; Clin Neurol Neurosurg 1997 Oct;99 Suppl 2:S36-8)
- 437.5 is a specific code that can be used to specify a diagnosis
- 437.5 contains 4 index entries
Nonpyogenic thrombosis of intracranial venous sinus- 437.6 is a specific code that can be used to specify a diagnosis
- 437.6 contains 7 index entries
Transient global amnesia- A syndrome characterized by a transient loss of the ability to form new memories. It primarily occurs in middle aged or elderly individuals, and episodes may last from minutes to hours. During the period of amnesia, immediate and recent memory abilities are impaired, but the level of consciousness and ability to perform other intellectual tasks are preserved. The condition is related to bilateral dysfunction of the medial portions of each TEMPORAL LOBE. Complete recovery normally occurs, and recurrences are unusual. (From Adams et al., Principles of Neurology, 6th ed, pp429-30)
- 437.7 is a specific code that can be used to specify a diagnosis
- 437.7 contains 2 index entries
Other ill-defined cerebrovascular disease- 437.8 is a specific code that can be used to specify a diagnosis
- 437.8 contains 35 index entries
Unspecified cerebrovascular disease- A broad category of disorders characterized by impairment of blood flow in the arteries and veins which supply the brain. These include CEREBRAL INFARCTION; BRAIN ISCHEMIA; HYPOXIA, BRAIN; INTRACRANIAL EMBOLISM AND THROMBOSIS; INTRACRANIAL ARTERIOVENOUS MALFORMATIONS; and VASCULITIS, CENTRAL NERVOUS SYSTEM. In common usage, the term cerebrovascular disorders is not limited to conditions that affect the cerebrum, but refers to vascular disorders of the entire brain including the DIENCEPHALON; BRAIN STEM; and CEREBELLUM.
- 437.9 is a specific code that can be used to specify a diagnosis
- 437.9 contains 14 index entries
