ABSTRACT Background: Cognitive impairments induced by substance use disorders (SUDs) are broadly documented. Evidence for these effects ought to be considered with regard to the new classification of neurocognitive disorders (NCDs). Failing to assess diagnostic criteria for NCD could be a limitation of studies addressing the effects of SUDs on cognition, resulting in misdiagnosis and inaccurate prevalence estimation. Methods: A systematic search of original articles (2000–2016) was conducted in Web of Knowledge and Science Direct. Key terms were: NCD and associated terms, and SUDs or alcohol, marijuana, cocaine and inhalants. Results: 59 cross-sectional and five prospective studies were reviewed. Criterion A.1 (evaluation of subjective concern of cognitive decline relative to a baseline), and criterion B (evaluation of impairment in daily life activities due to cognitive impairment) were not effectively evaluated in any of the studies. All studies addressed criterion A.2 (objective evidence of cognitive decline) via heterogeneous neuropsychological testing. Criteria C (absence of delirium) and D (absence of other possible etiologies) were frequently considered for control of confounding effects, mostly via methodological procedures (e.g. abstinence before evaluation, and exclusion of participants with comorbid disorders). Conclusion: These findings highlight the need to develop and disseminate standard procedures for assessment of substance-induced NCD.

The aim of this paper is to analyze the effects of intensive speech therapy intervention in a case of progressive non-fluent aphasia (PNFA). This is a dementia syndrome characterized by a progressive deficit in expressive language fluency and syntactic analysis, and by agrammatism and phonemic paraphasias. Although in the early stages there are no alterations in memory, comprehension, or visual processing, personality changes can slightly occur. To analyze the effects of speech therapy in this syndrome, a single case design with pre- and post-test was used. The participant was a male patient of 84 years with PNFA, who for twelve months received weekly speech therapy to stimulate the phonological, lexical and syntactic processing. He underwent neuropsychological assessment in three stages: six months before the onset of therapy, six months after therapy started and after completing 12 months of intervention. Assessment involved linguistic processing, general cognition, neuropsychiatric symptoms, quality of life (QOL) and activities of daily living (ADL). As a result of therapy, the patient showed a slight improvement in language prosody, fluency, and content of spontaneous speech, and a significant improvement in repetition, reading aloud, and oral-phonatory praxis. Other aspects of cognitive functioning (orientation, verbal naming, praxis, and memory) remained stable; ADLs and QOL improved. It is concluded that prolonged speech therapy can improve language processing and have a positive impact on other cognitive and socio-emotional processes in PNFA. This 12-month therapeutic stimulation not only slowed cognitive decline, but allowed to see maintenance of achievements and improvement of symptoms, which can be regarded as a success in PNFA treatment, considering the rapid progression of the disease.

Background. The Montreal Battery of Evaluation of Amusia (MBEA) is a newly developed instrument to assess music perception and memory, associated to temporal lobe functioning. The non-symptomatic temporal lobe epilepsy is a prevalent condition in Mexico, and it gives an opportunity to test the MBEA, considering the fact that epileptic seizures can cause neuropsychological impairment according to lobar localization and hemispherical lateralization of the epileptogenic foci. Objective. To explore the psychometric and diagnostic properties of the MBEA. Method. Two non-probabilistic samples of 31 control subjects and 22 cases with non-symptomatic temporal lobe epilepsy were assessed with the MBEA. Data from the original validation were used to compare with the control group. Results. Analysis with t test showed significantly lower performances in the case group relative to controls, and a general lower performance of controls compared to the norm. There was no significant difference in performance between cases with left epileptogenic foci and cases with right epileptogenic foci. ROC curve analysis showed questionable properties of sensitivity and specificity in the MBEA. Discussion and conclusion. Impairments in music perception were found in cases, although theoretical inconsistences with respect to relation between impaired functions were also detected. The performance of the control group relative to the norm aims to the continuation of the validation process, considering cultural differences. The MBEA seems to be a poor measure in terms of sensibility and specificity for the detection of amusic impairments in subjects with non-symptomatic temporal lobe epilepsy, and its utility for determining hemispheric lateralization of epileptogenic foci remains uncertain.

There is little evidence of cognitive impairment to define the profile of patients with Lacunar Infarction (IL). The purpose of this study was to identify the neuropsychological disorders in these patients. The sample consisted of 16 patients with IL and 16 healthy control participants with an average age of 63 ± 9.41 and 64.75 ± 9.06 years, and average schooling of 7.55 ± 4.34 and 7.94 ± 3.51, respectively. Cognitive function was assessed using a screening tool and a neuropsychological battery. Statistical analysis was carried out by the Kruskal-Wallis and Mann-Whitney U tests. Patients with IL are characterized by the alteration of domains such as planning, verbal fluency, attention switching, visoconstructive skill and information processing speed (p <0.050). The IL is related to the impairment of executive functioning and processing speed, due to the interruption of frontocortico-subcortical circuits associated with their proper performance.
