Quality of Episodic Memory
Tidsramme: 3 months
|
The Cognitive Drug Research (CDR) computerised battery tests is designed to evaluate the effects of novel compounds on the quality of cognitive functioning.
Quality of Episodic Memory measures the capability of maintaining information in episodic memory and is assessed as the sum of sensitivity indices from 4 memory tasks on the CDR computerised battery tests.
Values are calculated by a computer and higher scores mean better outcome.

Quality of Working Memory
Tidsramme: 3 months
|
The Cognitive Drug Research (CDR) computerised battery tests is designed to evaluate the effects of novel compounds on the quality of cognitive functioning.
Quality of Working Memory measures the capability of maintaining information in working memory and is assessed as the sum of sensitivity indices from 2 memory tasks on the CDR computerised battery tests.
Values are calculated by a computer and higher scores mean better outcome.

Quality of Memory
Tidsramme: 3 months
|
The Cognitive Drug Research (CDR) computerised battery tests is designed to evaluate the effects of novel compounds on the quality of cognitive functioning.
Quality of Memory is a combination of outcome measures Quality of Working Memory & Quality of Episodic Memory.
Values are calculated by a computer and higher scores mean better outcome.

Speed of Memory
Tidsramme: 3 months
|
The Cognitive Drug Research (CDR) computerised battery tests is designed to evaluate the effects of novel compounds on the quality of cognitive functioning.
Speed of Memory is assessed as the sum of speed measures from 2 memory tasks and 2 recognition tasks on the CDR computerised battery tests.
Values are calculated by a computer and higher scores mean better outcome.

Power of Attention
Tidsramme: 3 months
|
The Cognitive Drug Research (CDR) computerised battery tests is designed to evaluate the effects of novel compounds on the quality of cognitive functioning.
Power of attention measures speed and attention and is assessed from 3 attentional tasks on the CDR computerised battery tests.
Values are calculated by a computer and higher scores mean better outcome.

|
Continuity of Attention
Tidsramme: 3 months
|
The Cognitive Drug Research (CDR) computerised battery tests is designed to evaluate the effects of novel compounds on the quality of cognitive functioning.
Continuity of attention measures speed and accuracy and is calculated from 3 attentional tasks on the CDR computerised battery tests.
Values are calculated by a computer and higher scores mean better outcome.

NPI Total Score
Tidsramme: 3 months
|
The total score of Neuropsychiatric Inventory (NPI) was assessed by a caregiver interview.
10 behavioral areas were included: Delusions, Hallucinations, Agitation/Aggression, Depression/Dysphoria, Anxiety, Elation/Euphoria, Apathy/Indifference, Disinhibition, Irritability/Lability, and Aberrant Motor Behaviour.
Higher scores mean worse outcome.
Minimum value 0, maximum value 120.

Caregiver Distress Score
Tidsramme: 3 months
|
Caregiver distress score generated by adding together the scores of individual NPI distress questions of Neuropsychiatric Inventory NPI.
Higher scores mean worse outcome.
Minimum value 0, maximum value 120.
