Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Example Input: Context: A scale for the Assessment and Rating of Ataxia (SARA) was developed for evaluation of autosomal dominant cerebellar ataxias (ADCA) and was also recommended for clinical trials of Friedreich's ataxia patients (FRDA). FRDA, unlike ADCA, is characterized as being a sensory type of ataxia for which the disease-specific Friedreich ataxia rating scale (FARS) was developed. The objective of this study was to determine whether SARA and FARS scores are associated with posturographic parameters in FRDA patients.", 'Adult patients with genetically confirmed FRDA (n=11) and ADCA (n=13) were evaluated by SARA, FARS and posturography.', "FRDA patients' postural stability parameters, in stance with visual control, correlated with balance impairment in FARS (r=0.622; p<0.05) and SARA (r=0.735; p<0.05). Without visual control, only FARS correlated with balance impairment (r=0.732; p<0.05).
Answer: The SARA, in FRDA patients, correlates with stance with visual control but not without visual control which emphasizes sensory ataxia. This suggests that application of the SARA in Friedreich's ataxia patients according to posturography is possible but presumably limited and FARS, although being a more time consuming scale, may have advantages over SARA in FRDA patients.
Example Output: Is application of a Scale for the Assessment and Rating of Ataxia ( SARA ) in Friedreich 's ataxia patients according to posturography limited?

Example Input: Context: Psychomotor abnormalities characterize both unipolar (UP) depression and bipolar (BP) depression. We aimed to assess their neurobiological correlates in terms of motor activity (AL) and resting-state cerebral blood flow (rCBF) and investigate their association in BP, UP, and healthy controls (HC).', 'We enrolled 42 depressed patients (22 BP, 20 UP) and 19 HC matched for age, gender, education, income. AL and rCBF were objectively assessed with the use of wrist actigraphy and arterial spin labeling. Group differences and the association of AL and rCBF were computed.', 'Activity level was significantly reduced in patients, but no difference was found between BP and UP. Increased perfusion was found in BP compared with UP and HC, in multiple brain areas. We found positive correlations of rCBF and AL in BP and UP, in different parts of the insula and frontal regions. Only BP showed a cluster in the left precentral gyrus. In HC, only inverse correlations of AL and rCBF were found.
Answer: The differences in rCBF and in the localization of the clusters of positive AL/rCBF correlations between BP and UP suggest that different neural impairments may underlie motor symptoms in the two disorders, but finally converge in phenotypically similar manifestations.
Example Output: Do distinct resting-state perfusion patterns underlie psychomotor retardation in unipolar vs. bipolar depression?

Example Input: Context: If patients with idiopathic normal pressure hydrocephalus (INPH) also have depression, this could have important clinical ramifications in assessment and management of their cognitive function and response to shunting. In many dementias, depression is overrepresented, but the prevalence of depression in shunted patients with INPH is unknown.', 'The objective of this case-control study was to assess the prevalence of symptoms of depression in shunted INPH patients compared with population-based controls.', 'INPH patients consecutively shunted from 2008 to 2010 in Sweden were analyzed. Patients remaining after inclusion (within 60-85 years and not having dementia, ie, mini-mental state examination ≥23) had a standardized visit to their healthcare provider and answered an extensive questionnaire. Age- and sex-matched population-based controls underwent the same procedure. Symptoms of depression were assessed using the Geriatric Depression Scale 15 (suspected depression defined as ≥5 points, suspected severe depression as ≥12 points). This study is part of the INPH-CRasH study.', 'One hundred seventy-six INPH patients and 368 controls participated. After adjustment for age, sex, cerebrovascular disease, and systolic and diastolic blood pressure, patients had a higher mean depression score (patients: 4.9 ± 3.7 SD, controls: 1.9 ± 2.3 SD; OR 1.4, 95% CI 1.3-1.6, P < .001), more patients had suspected depression (46% vs 13%, OR 6.4, 95% CI 3.8-10.9, P < .001), and more patients had suspected severe depression (7.3% vs 0.6%, OR 14.4, 95% CI 3.0-68.6, P < .005).
Answer: Symptoms of depression are overrepresented in INPH patients compared with the population, despite treatment with a shunt. Screening for depression should be done in the evaluation of INPH patients in order to find and treat a coexisting depression.
