Increased Intracranial Pressure (ICP)
The skull is a rigid compartment. Any added volume (tumor, blood, edema, or CSF) raises the Intracranial Pressure (ICP). ICP is considered elevated when it is greater than 20 mmHg (normal is typically less than 15 mmHg).
The relationship between ICP and Cerebral Perfusion Pressure (CPP) is critical: CPP = MAP − ICP. A rising ICP reduces CPP, leading to cerebral ischemia.
Causes of Elevated ICP
- Intracranial mass (tumor, hematoma, large infarct)
- Cerebral edema
- Hydrocephalus

| NOT NULL | name VARCHAR(50) NOT NULL | Ensures a column cannot have an empty value. |
| UNIQUE | email VARCHAR(50) UNIQUE | Ensures all values in a column are different. |
| PRIMARY KEY | id INT PRIMARY KEY | Uniquely identifies each row (implies NOT NULL + UNIQUE). |
