The brain is complex. It monitors the state of the body and its environment, controls the body’s motion and also performs many of the higher level cognitive functions that allow us to think, plan, and accomplish the tasks in our daily lives. Cognitive functions are the basis for our activities of daily living and include the ability to shop, talk on the telephone, manage finances, drive, as well as to learn something new. While it is true that most brain functions involve much coordination between different brain regions, we also know that certain brain functions can be tested separately. Neuropsychologists have defined a set of basic cognitive functions that underlie brain wellness.
We can assess with computer based testing which follows the neuropsychological tradition by measuring:
- Executive Function
- Visual Spatial
- Verbal Function
- Problem Solving
- Working Memory
In addition, we utilize questionnaire-based scales for psychosocial factors that may impact brain wellness.
Transcranial Doppler (TCD) are types of Doppler ultrasonography that measure the velocity of blood flow through the brain’s blood vessels by measuring the echoes of ultrasound waves moving transcranially (through the cranium).
These modes of medical imaging conduct a spectral analysis of the acoustic signals they receive and can therefore be classified as methods of active acoustocerebrography. They are used as tests to help diagnose emboli, stenosis, vasospasm from a subarachnoid hemorrhage (bleeding from a ruptured aneurysm), and other problems. The tests are effective for detecting sickle cell disease, ischemic cerebrovascular disease, subarachnoid hemorrhage, arteriovenous malformations, and cerebral circulatory arrest. The tests are often used in conjunction with other tests such as MRI, MRA, carotid duplex ultrasound and CT scans.
