You will be shown inclusion or exclusion criteria for a clinical trial. Given these criteria, your task is to extract all unique entities of the following types: ["Observation", "Condition", "Procedure", "Drug", "Temporal", "Multiplier", "Qualifier", "Negation", "ReferencePoint", "Scope", "Value", "Mood", "Device", "Visit", "Measurement", "Person"].

Please return the output as a JSON object of the format: {"Condition" : ["breast cancer", ...], "Device" : ["ports", ...], "Drug" : ["Atenolol", ...], "Measurement" : ["blood pressure", ...], "Mood" : ["suspected", ...], "Multiplier" : ["more than two", ...], "Negation" : ["no", ...], "Observation" : ["history", ...], "Person" : ["male", ...], "Procedure" : ["surgery", ...], "Qualifier" : ["severe", ...], "ReferencePoint" : ["enrollment", ...], "Scope" : ["infection", ...], "Temporal" : ["one day", ...], "Value" : ["50%", ...], "Visit" : ["ICU", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

1. Absence of objectionable cognitive impairment or presence of dementia of severe degree defined by CDR score > 2.0. 
2. Unavailability of brain MRI (in case of absolute contraindications, the use of cranial CT is allowed). 
3. Expected poor compliance with the study protocol. 
4. Past diagnosis of major depression, schizophrenia, major anxiety syndrome, or manic- depressive illness. 
5. Diagnosis of degenerative cognitive impairment based on clinical and/or neuroradiological findings (i.e., patients with prevailing memory impairment, or with medial temporal atrophy on brain MRI in absence of evident vascular abnormalities; i.e., Alzheimer disease as defined using the National Institute of Neurological and Communicative Disorders and Stroke/Alzheimer's Disease and Related Disorders Association criteria, Parkinson disease, Huntington disease, frontotemporal dementia). 
6. Diagnosis of cognitive impairment from other causes (i.e., vitamine B12 and folic acid deficiency, thyroid disorders, metabolic diseases, head trauma, tumor or infections of the central nervous system, normal pressure hydrocephalus). 
7. Medical conditions expected to progress, recur, or change to such a degree to interfere with the assessment of the clinical and mental status. 
8. Clinically relevant cardiac or pulmonary insufficiency. 
9. Relevant electrocardiograph abnormalities; bradycardia (50 bpm) or tachycardia (120 bpm) under resting conditions. 
10. Myocardial infarction within the past 6 months. 
11. Stroke still requiring neurological rehabilitation. 
12. Severe/untreated blood pressure (systolic 180 mm Hg, diastolic 95 mm Hg). 
13. Clinically relevant liver function impairment. 
14. Insulin-dependent diabetes mellitus. 
15. Idiopathic epilepsy and anti-epileptic treatment. 
16. Severe anemia (Hb <10 mg/dL). 
17. Severe gastrointestinal disease. 
18. Cancer. 
19. Known intolerance to study drugs. 
20. Coexistent serious illnesses that would imply a drop-out before the end of the trial.
