Definition of Brain Drain There are various causes of brain drain, but they differ depending on the country that's experiencing it. The main causes include seeking employment or higher paying jobs, political instability, and to seek a better quality of life. Causes of brain drain can categorized into push factors and pull factors.

- 2. WHORL PATTERNS: A whorl pattern consists of a series of almost concentric circles. * A whorl pattern has two deltas *There are four types of whorl patterns: 1. Plain whorl, 2. Central Pocket Loop whorl, 3. Double Loop whorl, 4. Accidental whorl*Whorl patterns account for @ 25% of fingerprints. In an arch pattern, ridges flow in one side and flow out theopposite side. There are no deltas in an arch pattern. *There are two types of arch patterns: 1. Plain arch, 2.

Brain abscess Causes. Brain abscesses commonly occur when bacteria or fungi infect part of the brain. As a result, swelling and irritation (inflammation) develop. Infected brain cells, white blood cells, live and dead bacteria, or fungi collect in an area of the brain. Tissue forms around this area and creates a mass, or abscess.

Cerebrospinal Fluid Leaks: The Causes and Symptoms Several conditions can result in a cerebrospinal fluid leak. For example, a patient may develop a CSF leak after sustaining a head injury. Leakage of the cerebrospinal fluid may occur after certain medical procedures. A leak may occur after a lumbar puncture, or spinal tap, which is a procedure in which a sample of the cerebrospinal fluid is drawn. In this case, the leakage occurs where the puncture was done. Some patients may develop a CSF leak after having surgery on the brain, spinal cord or head. Other causes of a cerebrospinal fluid leak include cervical bone spurs, epidural anesthesia and epidural steroid injections. A CSF leak can result in several different symptoms. Patients may have a headache, which MedlinePlus described as worsening when patients sit up, and improves when patients lie down.

- Two types of hydrocephalus are commonly described non-communicating hydrocephalus and communicating hydrocephalus, although there is evidence that communicating forms can lead to obstruction of CSF flow in many instances.ydrocephalus is usually due to blockage of cerebrospinal fluid (CSF) outflow in the ventricles or in the subarachnoid space over the brain. In a person without hydrocephalus, CSF continuously circulates through the brain, its ventricles and the spinal cord and is continuously drained away into the circulatory system.

- Cerebrospinal fluid (CSF) bathes the brain and is contained within a lining around the brain called the dura. These intracranial structures (structures within the brain cavity) are also separated from the sinuses by bone. When there is a hole in the dura and bone, CSF can then leak into the sinuses and cause a CSF leak.gain if the leak site cannot be found on imaging studies, dye placed into the spinal fluid, which mixes with the brain fluid, can be placed at the beginning of the repair surgery to identify the leak under direct visualization.

Hydrocephalus (Water on the Brain) Hydrocephalus is a condition that occurs when fluid builds up in the skull and causes the brain to swell. The name means “water on the brain.”. Brain damage can occur as a result of the fluid buildup. This can lead to developmental, physical, and intellectual impairments. It requires treatment to prevent serious complications. Hydrocephalus mainly occurs in children and adults over 60, but younger adults can get it too.

- Head banging enthusiasts all over the world take the news with a pinch of salt, but unfortunately, a new research that appeared in the latest issue of The Lancet confirms that headbanging can cause a chronic subdural haematoma, most commonly known as a blood clot in the brain.

- An abscess of the brain is usually the result of a bacterial or fungal infection. The infection will cause your brain to swell from the collection of pus and dead cells that form. A brain abscess can form when fungi, viruses, or bacteria reach the brain through a wound to the head or infection elsewhere in the body.

- Hydrocephalus is a brain condition that happens when cerebrospinal fluid (CSF) — the clear, watery fluid that surrounds and cushions the brain and spinal cord — can't drain from the brain. It then pools, causing a buildup of fluid in the skull.

Overview Brain hypoxia is when the brain isn’t getting enough oxygen. This can occur when someone is drowning, choking, suffocating, or in cardiac arrest. Brain injury and carbon monoxide poisoning are other possible causes of brain hypoxia. The condition can be serious because brain cells need an uninterrupted flow of oxygen to function properly.

- CSF Leaks. Kevin C. Welch, MD. Introduction. A disruption (a hole or tear) in the brain lining (called the dura) and the bone separating the brain and the sinuses will result in the drainage of fluid that normally surrounds the brain into the sinuses.This fluid is known as cerebrospinal fluid or CSF..Drainage of CSF into the sinuses can result in a multitude of problems, not to mention the often times annoying constancy of nasal dripping. This article discusses current concepts in the causes and diagnosis as well as treatment of CSF leaks. disruption (a hole or tear) in the brain lining (called the dura) and the bone separating the brain and the sinuses will result in the drainage of fluid that normally surrounds the brain into the sinuses.

CSF Leaks and Spontaneous Intracranial Hypotension Causes of Cerebrospinal Fluid Leaks. Cerebrospinal fluid can leak if there is a tear or hole in the membrane (thin tissue) that surrounds the brain and spinal cord. The most common reasons for the membrane to tear include: Certain head, brain, or spinal surgeries.

- Blockages are the most common cause of hydrocephalus. Cysts, tumors, or inflammation in the brain can impede the normal flow of CSF and create an unsafe accumulation. Symptoms of hydrocephalus can include: 1  large head size. 2  headaches. 3  seizures. 4  irritability. 5  excessive sleepiness. 6  incontinence. 7  poor appetite.

Hydrocephalus Hydrocephalus can be classified according to its cause: 1  Obstructive (non-communicating) hydrocephalus is caused by a blockage in the system of cavities (ventricles) in the brain. 2  Non-obstructive (communicating) hydrocephalus results from problems with cerebrospinal fluid being produced or absorbed.

Hydrocephalus Causes. Hydrocephalus is due to a problem with the flow of the fluid that surrounds the brain. This fluid is called the cerebrospinal fluid, or CSF. The fluid surrounds the brain and spinal cord, and helps cushion the brain. CSF normally moves through the brain and the spinal cord, and is soaked into the bloodstream.

Hydranencephaly Causes Hydranencephaly is an extreme form of porencephaly, which is characterized by a cyst or cavity in the cerebral hemispheres. Although the exact cause of hydranencephaly remains undetermined in most cases, the most likely general cause is by vascular insult such as stroke or injury, intrauterine infections, or traumatic disorders after the first trimester of pregnancy.

- Brain drain is still an issue in some Atlantic provinces such as New Brunswick, where a relative lack of jobs results in some of the highly educated moving to other provinces such as Ontario, Alberta, or British Columbia. Brain gain also occurs here, however, through immigration.

- When this fluid leaks from the brain or spinal cord, it is called a cerebrospinal fluid leak, or CSF leak. When the fluid leaks, the pressure around the brain and spinal cord drops. If you have a cerebrospinal fluid leak, the clear fluid may drain from your nose or ear(s). The most common symptom is a headache that improves when you lie down and worsens when you sit up. The headache may be accompanied by nausea, light sensitivity, and a stiff neck.

- Cerebrospinal Fluid Pathways. CSF flows out of the ventricles of the brain where it is produced and into the subarachnoid space of the brain and cord. Some CSF also flows down through a channel in the center of the cord called the central canal.The central canal, however, appears to close with age.In several key areas, the subarachnoid spaces surrounding the brainstem area are enlarged into cisterns. The cisterns cushion and protect the brain.ome CSF also flows down through a channel in the center of the cord called the central canal. The central canal, however, appears to close with age.
