Multiple sclerosis / demyelinating disease

Normalized thalamic volume relative to total intracranial volume, allowing for standardized assessment across individuals with different head sizes. This proportional measurement helps identify selective thalamic atrophy that might indicate specific neurological conditions including multiple sclerosis and certain dementias.

Normalized putamen volume as a proportion of total intracranial volume. This standardized measurement allows for more accurate detection of basal ganglia-specific changes independent of head size differences, which is important when evaluating movement disorders and certain neurodegenerative conditions.

Normalized volume of the left parietal lobe relative to total intracranial volume. This proportional measurement helps identify selective left parietal atrophy that might affect language processing, calculation abilities, and right-sided sensory integration.

Normalized volume of the left occipital lobe relative to total intracranial volume. This proportional measurement allows for standardized assessment of left occipital structure across individuals with different head sizes, helping detect selective atrophy that might affect specific visual processing functions.

The hippocampus is crucial for memory formation and spatial navigation. Atrophy of the hippocampus is a hallmark of Alzheimer's disease and can also occur in other forms of dementia. It is associated with memory loss and disorientation.

Represents the percentage or ratio of gray matter volume to total intracranial volume. This metric helps identify disproportionate gray matter loss that exceeds normal aging or is inconsistent with head size, potentially indicating neurodegenerative processes.

Normalized volume of the left frontal lobe relative to total intracranial volume. This proportional measurement allows comparison between individuals with different head sizes and helps assess selective frontal atrophy that might affect executive function, personality, and motor control on the right side of the body.

Normalized cortical gray matter volume relative to total intracranial volume, allowing for standardized assessment of cortical tissue across individuals with different head sizes.

Normalized volume of the caudate nucleus relative to total intracranial volume, allowing for meaningful comparisons between individuals with different head sizes. This proportional measurement helps identify caudate-specific changes that may indicate neurodegenerative disorders affecting executive function and movement control.

The ratio of total brain volume to total intracranial volume. This value typically decreases with age as brain atrophy progresses. Accelerated decline in this ratio beyond age-expected norms may suggest pathological brain volume loss.

Vitamin B12 is a water-soluble vitamin essential for the production of red blood cells, the synthesis of DNA, and the healthy functioning of the nervous system. It also supports brain function and energy metabolism. The body cannot make B12 on its own and relies on dietary sources such as meat, fish, eggs, and dairy. Excess B12 is stored in the liver, so deficiency can take time to develop but may lead to serious health issues if not addressed.
