Difference Between Sensitivity and Specificity Depending on the nature of the study, the importance of the two may vary. The ideal test should be able to deliver results with 100% sensitivity and 100% specificity but in a practical application it is difficult to be achieved. In most incidents, a trade between the two is essential to build a reasonable foundation to the reliability of the test results. Sensitivity.

Researchers for the first time have shown that drinking beet juice can increase blood flow to the brain in older adults -- a finding that could hold great potential for combating the progression of dementia.

- 1 Tumors in some parts of the brain may block cerebrospinal fluid from flowing out of the brain. New blood vessels growing in and near the tumor can also lead to swelling.  High altitudes: Although researchers don't know the exact causes, brain swelling is more likely to occur at altitudes above 4,900 feet. This type of brain edema is usually associated with severe acute mountain sickness (AMS) or high-altitude cerebral edema (HACE).

- Lewy body disease, one of the most common causes of dementia in older adults; But neurologic conditions are not the only cause. In fact, several non-neurogenic causes of the condition include: Heart attack; Aortic stenosis; Vasodilation; Drugs that can cause orthostatic hypotension include: Diuretics; Antihypertensive drugs; Tricyclic antidepressants

- 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. The flow of CSF is blocked.

What is hydrocephalus in elderly people? Hydrocephalus (water on the brain) is an excess of cerebrospinal fluid around the brain. Typically, the ventricles (cavities in the center of the brain) that secrete this fluid are greatly enlarged. Spinal fluid circulates around the spinal cord and is absorbed by veins on the external surface of the brain. Congenital hydrocephalus is usually diagnosed shortly after birth, but normal-pressure hydrocephalus occurs in a small number of elderly people. This condition can result from head trauma, brain hemorrhage, or meningitis (inflammation of the membrane covering the brain), but most cases occur spontaneously without an obvious preceding illness.

Hydrocephalus Not to be confused with Hypocephalus or Hydranencephaly. Hydrocephalus is a condition in which there is an abnormal accumulation of cerebrospinal fluid (CSF) within the brain. This typically causes increased pressure inside the skull. Older people may have headaches, double vision, poor balance, urinary incontinence, personality changes, or mental impairment.

- Any excess CSF usually drains away from the brain and is absorbed by the body. For people with hydrocephalus, this doesn't happen, and the fluid instead builds up in the ventricles. Too much cerebrospinal fluid puts a harmful amount of pressure on tissues in the brain - treatment is needed to release this pressure.

Neurosarcoidosis White matter hyperintensities (WMH) lesions on T2 and fluid attenuated inversion recovery (FLAIR) brain MRI are very common findings in elderly cohorts and their prevalence increases from 15% at the age of 60 to 80% at the age of 80 [1–4].

Cerebrospinal fluid Hydrocephalus is an abnormal accumulation of cerebrospinal fluid (CSF) in the ventricles, or cavities, of the brain, which may cause increased intracranial pressure (ICP) inside the skull.SF circulates within the ventricular system of the brain. The ventricles are a series of cavities filled with CSF, inside the brain. The majority of CSF is produced from within the two lateral ventricles.

Funeral Thank-You Notes Thank-you notes for acts of kindness - in addition to attending the funeral. It is customary for the bereaved - or someone on his behalf - to write handwritten thank-you notes in acknowledgment of: personal sympathy notes, flowers, Mass cards, gifts of food and help with daily activities.

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.

Hydrocephalus and shunts Hydrocephalus is a build-up of fluid in the brain. The excess fluid leads to increased pressure on the brain which can cause damage to the brain tissue. In the past, hydrocephalus was sometimes referred to as ‘water on the brain’ (the word hydrocephalus comes from the Greek words for water and head). However, the excess fluid is cerebrospinal fluid (CSF), not water.

Adult-onset Hydrocephalus Hydrocephalus can occur at any age, but is most common in infants and adults age 60 and older. It affects adult males and females, as well as people of different races, about equally. Experts believe that normal pressure hydrocephalus accounts for five to six percent of all dementia cases.

Low Blood Flow Ages Brain Faster Blood Flow and the Brain. As the brain ages, it starts to shrink or “atrophy,” and the decrease in volume is considered a sign of brain aging, the researchers say in a news release. More severe brain atrophy occurs in people with dementia, such as Alzheimer’s disease.

- The study included 515 hospital or nursing home patients age 50 years or older with dementia or Parkinson disease who aspirated on thin liquids during videofluoroscopy. The patients were randomized to drink all liquids using a chin-down position, or to drink nectar-thick liquids, or to drink honey-thick liquids.

Nutrition Problems in the Elderly Dehydration is common in the elderly for a number of reasons. The elderly have a reduced ability to conserve water, are less attuned to their thirst, and may avoid drinking fluids because of overactive bladder problems.

Lack of Strong Thirst Signals Leads Elderly to Drink Too Little PET scans of areas of their brains activated by thirst showed reactions -- particularly in the cingulate cortex. In the elderly, drinking a much smaller volume of water is needed to cause that area of brain activation to subside, said Egan, who is an expert on neuro-imaging.

What is cerebral edema? Cerebral edema is a dangerous condition where the brain's water content rises, causing the pressure to rise in the skull. Unlike swelling in other parts of the body, where there is room for extra fluid (think of a sprained ankle), the brain is protected by a hard, inflexible skull that can expand very little.

Chronic Subdural Hematoma This is usually the result of a head injury. A collection of blood then forms over the surface of the brain. In a chronic subdural collection, blood leaks from the veins slowly over time, or a fast hemorrhage is left to clear up on its own. A subdural hematoma is more common in the elderly because of normal brain shrinkage that occurs with aging. This shrinkage stretches and weakens the bridging veins. These veins are more likely to break in the elderly, even after a minor head injury.

Hydrocephalus In these cases, brain tissue may actually shrink. NPH is an abnormal increase of cerebrospinal fluid in the brain's ventricles that may result from a subarachnoid hemorrhage, head trauma, infection, tumor, or complications of surgery. However, many people develop NPH when none of these factors are present. An estimated 375,000 older Americans have NPH.

Watch for 'water on the brain' in older adults Fortunately, once NPH is confirmed, chances are it can be treated. Sometimes referred to as water on the brain, NPH is a buildup of cerebrospinal fluid (CSF) in the brain of older adults that leads to a gradual deterioration of motor skills and/or cognitive function.

- Less blood flow means that the brain tissue can be irreversibly injured, which is referred to as ischemic injury.. Some MRI reports may state that perivascular chronic ischemic white matter disease of aging is seen.We do know that we see increasing amount of these changes with age and see greater amounts of change in patients who have high blood pressure and diabetes.hite matter change is a very common finding on an MRI scan. Frequently, these changes are seen in patients who have/have had hypertension, stroke, migraine headaches, or other medical conditions. As the brain ages, we tend to see a change in appearance around the fluid filled spaces (the ventricles).
