- Differential diagnosis
the process of differentiating between two or more conditions which share similar signs or symptoms
- Agraphia
inability to write letters, symbols, words, or sentences, resulting from damage to various parts of the brain
- Apraxia
inability to write letters, symbols, words, or sentences, resulting from damage to various parts of the brain
- Ataxia
the loss of full control of bodily movements
- Aphasia
loss of ability to understand or express speech, caused by brain damage
- Dysarthria

- Nystagmus
rapid involuntary movements of the eyes
- Diplopia
double vision
- Digit span
repeating a string of integers forward and backward
- Recent memory
recalling information of three items or a brief story after a delay of 3 to 5 minutes
- Remote memory
remembering long term historical or verifiable personal events
- Anterograde amnesia
impaired memory of new facts and events occurring after lesion onset
- Retrograde amnesia
impaired memory of events for a period of time immediately before lesion onset, with relative sparing of earlier memories
- Hemineglect
abnormality in attention to one side of the world that is not due to a primary sensory or motor lesion
- Major depression
a mental condition characterized by a persistently depressed mood and long-term loss of pleasure or interest in life, often with other symptoms such as disturbed sleep, feelings of guilt or inadequacy, and suicidal thoughts
- Visual acuity

- Somatization disorder
a disorder when patients have multiple somatic complaints that change over time
- Malingering
exaggerate or feign illness in order to escape duty or work
- Functional MRI (fMRI)
- a specific type of MRI that measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases
- T-1 weighted image
a MRI with the appearance like that of an anatomical brain specimen i.e. gray matter is gray and white is white
- T-2 weighted image
a MRI with the appearance like that of an anatomical brain specimen i.e. opposite a T-1 weighted image where gray matter is white and white matter is gray
- Electroencephalogram
a test or record of brain activity produced by electroencephalography
