Overview

Aim:
Our intention was to create a simple visual evaluation of parietal atrophy on MRI of the brain useful in identify­­ing neurodegenerative dementias, especial­ly Alzheimer‘s dis­ease. We as­ses­sed the changes of the parietal regions dur­­ing natural aging.

Patients and methods:
We created a new rat­­ing scale that we named the Parietal atrophy score. This method is based on semiquantitativescor­­ing of three structures on coronal slices in the entire parietal lobe: parietal gyri, sulcus cingularis posterior and precuneus. Each structure was rated accord­­ing to the visual clas­sification size as 0 – a normal size without atrophy, 1 – a borderline find­­ing or 2 – a considerable atrophy. These ratings were sum­marized into one score for each hemisphere and then these two were integrated into one score for the entire brain. Us­­ing a visual rat­­ing scale, we clas­sified the parietal regions in 74 elderly subjects with a normal Mini-Mental State Examination score (29 ± 1 point) with a wide range of ages between 48– 87 years.

Results:
Increas­­ing age is as­sociated with a mild progression of the parietal lobe atrophy (r = 0.2; p = 0.05). The over­all score of the parietal tis­sue was not as­sociated with education, gender or hand dominance.

Conclusion:
Our new visual rat­­ing system of parietal atrophy is an easy and fast method for use in clinical practice. Natural ag­­ing is accompanied with negligible parietal atrophic changes.

Key words:
parietal atrophy – magnetic resonance imaging – Alzheimer‘s disease – normal aging – sulcus cingularis posterior – precuneus – parietal gyri
