Tests could include:
 |
The health care provider may do tests to rule out other diseases. Magnetic resonance imaging (MRI) might show shrinking of the brainstem.
|
|
PSP is sometimes mistaken for Parkinson's disease , which is also associated with stiffness, frequent falls, slurred speech, difficulty swallowing, and decreased spontaneous movement. The facial expression in Parkinson's, however, is blank or mask...
|
|
Lab tests and neuroimaging can be performed to eliminate other possible causes. One specific high resolution neuroimaging study called PET ( positron emission tomography ) scan can provide information about blood flow and oxygen supply to the brai...
|
|
A neurological examination is an essential component of a comprehensive physical examination . It is a systematic examination that surveys the functioning of nerves delivering sensory information to the brain and caring motor commands (Peripheral ...
|
|
During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with ha...
|
|
The health status of populations and of individuals is assessed for many reasons. Assessing needs for care helps guide the allocation of resources— diagnostic assessments guide treatment, prognostic assessments contribute to planning, and assessin...

|
Single photon emission computed tomography (SPECT) is an imaging study that uses radioactive materials injected through a vein that will pass into the brain generating a high-resolution brain image.
|
|
Single proton (or photon) emission computed tomography (SPECT) allows a physician to see three-dimensional images of a person's particular organ or body system. SPECT detects the course of a radioactive substance that is injected, ingested, or inh...
|
|
A positron emission tomography (PET) scan is an imaging test that uses a radioactive substance (called a tracer) to look for disease in the body. Unlike magnetic resonance imaging (MRI) and computed tomography (CT) scans, which reveal the structur...
|
|
Positron emission tomography (PET) is a highly specialized imaging technique using short-lived radiolabeled substances to produce powerful images of the body's biological function.
|
|
A heart positron emission tomography (PET) scan is an imaging test that uses a radioactive substance (called a tracer) to look for disease or poor blood flow in the heart. Magnetic resonance imaging (MRI) and computed tomography (CT) scans reveal ...
|
|
A lung positron emission tomography (PET) scan is an imaging test that uses a radioactive substance (called a tracer) to look for disease in the lungs, especially lung cancer. Unlike magnetic resonance imaging (MRI) and computed tomography (CT) sc...
|
|
Positron emission tomography (PET) is a non-invasive scanning technique that utilizes small amounts of radioactive positrons (positively charged particles) to visualize body function and metabolism .
|
|
The positron emission tomography ( PET ) unit is a device used to produce images of the body that reflect biochemical changes taking place in the body. Among the body imaging technologies used in medicine, the PET unit is characterized by its use ...
|
|
Positron emission tomography (PET) is a non-invasive scanning technique that utilizes small amounts of radioactive positrons (positively charged particles) to visualize body function and metabolism.
|
 |
Positron emission tomography (PET) is a scanning technique used in conjunction with small amounts of radiolabeled compounds to visualize brain anatomy and function. A PET scan showing brain activity while patient recognizes faces—left sides at lef...

 |
Positron emission tomography (PET) is a highly specialized imaging technique using short-lived radiolabeled substances to produce extremely high resolution images of the body's biological function.
|
|
Positron emission tomography (PET) is a noninvasive scanning technique that utilizes small amounts of radioactive positrons (positively charged particles) to visualize body function and metabolism.
|
 |
A magnetic resonance imaging (MRI) scan of the head is a noninvasive method to create detailed pictures of the brain and surrounding nerve tissues. Unlike x-rays and computed tomographic (CT) scans, which use radiation, MRI uses powerful magnets a...
|
 |
Magnetic resonance imaging (MRI) scanners rely on the principles of atomic nuclear-spin resonance. Using strong magnetic fields and radio waves, MRI collects and correlates deflections caused by atoms into images. MRIs (magnetic resonance imaging ...
|
|
Traumatic brain injury (TBI) is the result of physical trauma to the head causing damage to the brain. This damage can be focal, or restricted to a single area of the brain, or diffuse, affecting more than one region of the brain. By definition, T...
|
 |
The brain is the part of the central nervous system (CNS) inside the skull (the part outside the skull is the spinal cord ). It gives rise to cognitive thought processes and controls various body functions including muscular activity, speech, sigh...
|
 |
A brain tumor is an abnormal growth of tissue, either malignant (cancerous) or benign (noncancerous), in the brain. Each year, more than 17,000 brain tumors are diagnosed in the United States.
|
 |
The brain is a large mass of soft nervous tissue made up of both neurons and supporting glial cells lying within the cranium of the skull. The brain contains both gray and white matter. Gray matter is primarily nerve cell bodies, whereas white mat...
|
 |
The brain is the part of the central nervous system located in the skull. It controls the mental processes and physical actions of a human being.
|
|
Congenital brain defects are a group of disorders of brain development.
|
 |
A brain tumor is an abnormal growth of tissue in the brain. Unlike other tumors, brain tumors spread by local extension and rarely metastasize (spread) outside the brain. A benign brain tumor is composed of non-cancerous cells and does not metasta...
|
|
A brain biopsy is the removal of a small piece of brain tissue for the diagnosis of abnormalities of the brain, such as Alzheimer's disease , tumors, infection, or inflammation.
|
|
Brain abscess is a bacterial infection within the brain.
|
 |
Congenital brain defects are a group of disorders of brain development that are present at birth.
|
 |
Like all other parts of the body, the brain and central nervous system are made up of cells that ordinarily grow and divide to create new cells as needed. This is usually an orderly process; but when cells lose their ability to grow normally or to...
|
|
Part of the central nervous system located in the skull. Controls mental and physical actions of the organism. The brain, with the spinal cord and network of nerves, controls information flow throughout the body, voluntary actions, such as walking...
