Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Q: Abstract: Men and women with dementia of the Alzheimer type (DAT) had more brain atrophy and ventricular dilatation, measured by quantitative CT, than did respective age- and sex-matched healthy controls (p less than 0.05). The male DAT patients with mild dementia had a larger mean third ventricle volume, whereas male patients with severe dementia had larger lateral and third ventricle volumes, more CSF, and less gray matter than did controls. Statistically significant and appropriate correlations between several dementia scales and CT measures in the DAT patients indicated that brain atrophy and ventricular dilatation were related to the severity of dementia.
Which is the apt title for the abstract? option1: Quantitative computed tomography in dementia of the Alzheimer type. option2: Histones and metal-binding domains.
A:
Quantitative computed tomography in dementia of the Alzheimer type.
