there is a 4mm focus of high T2 signal intnesity within the subcortal white matter of the right frontal lobe inferioly and latrally which demonstrates no associated mass effect, diffusion restriction or enhancement.it may represent a minimal degree of nonspecific demyelinization or sequela of prior trauma, what does this mean, i had this mri because of a headache with blurred vision and right side of my lip was numb since then ive had several other tests and mri tests , a bone scan and blood work, bone scan showed hot spots, but the report and additional mri was clear, i scared that im being misdiagnosed what other tests should be done and what other doctor should i try to be seen by
The following functions performed by the frontal lobe would be of great help to you.
The frontal lobes are considered our emotional control center and home to our personality. There is no other part of the brain where lesions can cause such a wide variety of symptoms (Kolb & Wishaw, 1990). The frontal lobes are involved in motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, and social and sexual behavior. The frontal lobes are extremely vulnerable to injury due to their location at the front of the cranium, proximity to the sphenoid wing and their large size. MRI studies have shown that the frontal area is the most common region of injury following mild to moderate traumatic brain injury (Levin et al., 1987).
There are important asymmetrical differences in the frontal lobes. The left frontal lobe is involved in controlling language related movement, whereas the right frontal lobe plays a role in non-verbal abilities. Some researchers emphasize that this rule is not absolute and that with many people, both lobes are involved in nearly all behavior.
Disturbance of motor function is typically characterized by loss of fine movements and strength of the arms, hands and fingers (Kuypers, 1981). Complex chains of motor movement also seem to be controlled by the frontal lobes (Leonard et al., 1988). Patients with frontal lobe damage exhibit little spontaneous facial expression, which points to the role of the frontal lobes in facial expression (Kolb & Milner, 1981). Broca's Aphasia, or difficulty in speaking, has been associated with frontal damage by Brown (1972).
