• Any other condition or clinically significant abnormal findings on the physical or neurological examination, medical and psychiatric history, at screening or at baseline that, in the opinion of the Investigator, would make the subject unsuitable for the study.
• Potential symptomatic causes of cognitive impairment including but not limited to
• abnormal thyroid function test at screening (TSH)
