Alzheimer's disease (AD), also known in medical literature as Alzheimer disease, is the most common form of dementia. There is no cure for the disease, which worsens as it progresses, and eventually leads to death. It was first described by German psychiatrist and neuropathologist Alois Alzheimer in 1906 and was named after him.

What is a brain imaging technique?
A brain imaging technique is a method used to visualize and examine the structure and function of the brain. Examples include MRI, CT scan, PET scan, and fMRI. These techniques are valuable in diagnosing neurological disorders, studying brain activity, and understanding the brain's anatomy.
What procedure involves measurement of the dimensions of the brain?
The procedure that involves the measurement of the dimensions of the brain is called neuroimaging, with techniques such as MRI (magnetic resonance imaging) and CT (computed tomography) scans being commonly used. These imaging methods allow for detailed visualization and quantification of brain structures, including volumes, surface areas, and other anatomical features. Neuroimaging is crucial for diagnosing conditions, monitoring brain health, and conducting research in neuroscience.
Which diagnostic machines uses magnetic fields and radio waves to produce images of the brain?
Magnetic resonance imaging (MRI) machines use magnetic fields and radio waves to produce detailed images of the brain. This technology is non-invasive and provides high-resolution images for diagnosing various neurological conditions.
What contrast is use in brain?
In brain imaging, contrast refers to the differences in signal intensity that help distinguish between various tissues and structures. Commonly used contrasts include T1 and T2-weighted imaging in MRI, which highlight different properties of brain tissues. Additionally, contrast agents like gadolinium can be injected to enhance visualization of blood vessels and abnormalities. These contrasts aid in diagnosing conditions such as tumors, strokes, and neurodegenerative diseases.
How brain scans detect ms?
Brain scans, particularly magnetic resonance imaging (MRI), are crucial for diagnosing multiple sclerosis (MS) as they can reveal lesions or plaques in the brain and spinal cord. These lesions are caused by the demyelination characteristic of MS, where the immune system attacks the protective covering of nerve fibers. MRI can also help assess the extent of disease progression and monitor treatment efficacy by detecting new or changing lesions over time. Advanced imaging techniques like diffusion tensor imaging (DTI) may also provide insights into the integrity of white matter in the brain.
A 67-year-old patient suffering from profound memory loss and confusion may be evaluated for suspected alzheimer's disease what medical imaging technique may be used for this evaluation?
A brain imaging technique called MRI (Magnetic Resonance Imaging) may be used to evaluate the brain structure, such as looking for shrinkage in certain areas characteristic of Alzheimer's disease. Additionally, a PET (Positron Emission Tomography) scan may be used to assess brain function and metabolism, which can also help in diagnosing Alzheimer's disease.
Which brain imaging technique records the oscillations of the brain's neurons?
EEGs
Which imaging technique is used to determine cardiac or cerebral perfusion plus brain imaging for epilepsy dementia and recurrent brain tumors?
PET
Which of the following brain imaging techniques produce the most detailed picture of brain structure?
Functional Magnetic Resonance Imaging (fMRI)
What is the use of thermal imaging to detect tumours in the brain?
remember it for ever as 40% of it is by imaging
How is schizoaffective disorder diagnosed?
There are no accepted tissue or brain imaging tests or techniques to diagnose. Instead, physicians look for the hallmark signs and symptoms.and they attempt to rule out other illnesses or conditions that may produce similar symptoms.
What is a MRI of brain and spine?
An MRI (Magnetic Resonance Imaging) of the brain and spine is a non-invasive imaging technique that uses strong magnetic fields and radio waves to create detailed images of the brain and spinal cord. It helps in diagnosing various conditions such as tumors, infections, degenerative diseases, and structural abnormalities. The procedure is painless and does not involve exposure to ionizing radiation, making it a safe option for patients. MRI images provide critical information that aids in treatment planning and monitoring.
