INTRODUCTION. Temporal orientation is a component of most screening tests for diagnosing cognitive impairment. Correct temporal orientation involves activating both semantic information (concepts of the calendar date) and episodic information (remembering the current date). AIMS. The aim of this study was to assess the diagnostic usefulness of a technique for evaluating temporal orientation, which was open-ended, and scoring the semantic and episodic information thus generated (0-10 points). SUBJECTS AND METHODS. A total of 24 subjects without impairment, 77 patients with mild cognitive impairment (MCI) and 62 patients with dementia were evaluated by means of a 30-point mini-mental/mini-examination, semantic verbal fluency test, global deterioration scale, mini-mental-type temporal orientation and open-ended temporal orientation tests. The areas under the curve (aROC), sensitivity and specificity for dementia and cognitive impairment at any degree (MCI and dementia) were analysed. RESULTS. Open-ended temporal orientation presented a greater area under the curve (a
0.90) for discrimination between patients with dementia and without dementia (MCI and without impairment) and an aROC of 0.83 for discrimination between patients with MCI or dementia and without impairment. For dementia, with a cut-off point equal to or below 6, sensitivity was 0.96 and specificity was 0.68, and for MCI with dementia, with a cut-off point equal to or below 7, sensitivity was 0.72 and specificity was 0.92. CONCLUSIONS. The usefulness, conciseness and strategic position of this technique in examining mental status make it suitable as an instrument for screening for cognitive impairment. It has a high level of sensitivity with low specificity for dementia and low sensitivity with high specificity for any degree of impairment.

Cognitive and emotional processes encompassing magnification of pain-related stimuli, feelings of helplessness, and a generally pessimistic orientation.
A progressive form of dementia characterized by the global loss of language abilities and initial preservation of other cognitive functions. Fluent and nonfluent subtypes have been described. Eventually a pattern of global cognitive dysfunction, similar to ALZHEIMER DISEASE, emerges. Pathologically, there are no Alzheimer or PICK DISEASE like changes, however, spongiform changes of cortical layers II and III are present in the TEMPORAL LOBE and FRONTAL LOBE.

A neurosurgical procedure that removes the anterior TEMPORAL LOBE including the medial temporal structures of CEREBRAL CORTEX; AMYGDALA; HIPPOCAMPUS; and the adjacent PARAHIPPOCAMPAL GYRUS. This procedure is generally used for the treatment of intractable temporal epilepsy (EPILEPSY, TEMPORAL LOBE).
A condition of low alertness or cognitive impairment, usually associated with prolonged mental activities or stress.
Cognitive disorders including delirium, dementia, and other cognitive disorders. These may be the result of substance use, trauma, or other causes.
Dementia describes a range of symptoms of cognitive decline. For example memory loss, problems with reasoning and communication skills, and a reduction in a person's abilities and skills in carrying out daily activities. There are about 820,000 peo...
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
