Pus Around The Brain (Subdural Empyema) Causes and Symptoms

What is a subdural empyema? A subdural empyema is a collection of pus in the subdural space, the naturally occurring space between the dura and arachnoid mater (outer and middle meningeal layer). This is a consequence of an infection and often spreads from neighboring sites like the paranasal sinuses. Most cases occur >> Read More ...

Brain Abscess Location, Causes and Symptoms

An abscess may originate in multiple sites within the cranial cavity and therefore the term intracranial abscess more accurately describes it. Since the largest part of the brain, the cerebrum, is more commonly affected the term brain abscess is synonymous with cerebral abscess. An abscess may also occur in the cerebellum >> Read More ...

Benign Fasciculation Syndrome (BFS) Constant Muscle Twitching

Neurological disorders are a diverse group of diseases affecting the brain, spinal cord and nerves. Many neurological symptoms are part of occasional experiences in normal healthy individuals and is not linked to any disease – like pain, dizziness, numbness, muscle twitches, cramps or even tremors. Some neurological >> Read More ...

Brain Injury and Different Types of Brain Inflammation

The term brain injury is often used synonymously with traumatic brain injury (TBI), however, it is important to note that not all types of injury to the brain tissue is associated with trauma. Similarly, head trauma will not always result in brain injury. Therefore brain injury should never be assumed by the degree of head >> Read More ...

Pressure on the Brain – Process, Causes and Symptoms

The pressure within the cranial cavity, the part of the skull that houses the brain, is maintained at a fairly constant level. This ensures that the brain can “float” in the CSF and be cushioned by the fluid without being compressed against the skull by its own weight, colliding with the skull bone during >> Read More ...

Brain Herniation – Causes of Different Types of Hernias

The cranial cavity houses the brain and related structures but it is a rigid compartment that will not accommodate expansion of the tissues and fluid within. The dural folds are also rigid dividers that compartmentalize the different parts of the brain.  The softer tissue of the brain therefore presses against the bone or >> Read More ...

Bleeding in Brain and Cranial Bleeds (Hematoma, Hemorrhage)

The brain lies within the cranial cavity – the large hollow area in the upper part of the skull. The bone of the skull protects the delicate brain tissue. Only narrow passages in the bottom of the cranial cavity allows the nerves, blood vessels and lymphatic vessels to travel to and from the brain. Therefore the >> Read More ...

Cerebrospinal Fluid (CSF) Circulation, Composition, Functions

What is cerebrospinal fluid? Cerebrospinal fluid (CSF) is a clear fluid that surrounds the brain and spinal cord. There is about 150 milliliters of CSF within the cerebral cavity that encloses the brain and spinal cord which allows the brain to “float” in the fluid. Formation of Cerebrospinal Fluid (CSF) Most >> Read More ...

Blood Flow in the Brain (Cerebral) and Control Mechanisms

Blood flow to the brain (cerebral blood flow) is essential to maintain consciousness and many vital functions. Unlike certain other parts of the body, a few seconds without blood flow will not be detrimental to functioning but in the brain, a lack of blood flow for even just 10 seconds will lead to unconsciousness. The >> Read More ...
