We identified the novel PSEN1 pathogenic mutation M84V in 3 patients belonging to a large kindred affected by autosomal dominant Alzheimer's disease (AD). The clinical phenotype was characterized by early onset dementia in 14 affected subjects over 3 generations. Detailed clinical, imaging and genetic assessment was performed. We highlighted the presence of unusual symptoms such as frontal executive syndrome, psychosis and spastic paraparesis in these patients. Spastic paraparesis has been reported in other PSEN1 mutations in adjacent codons, suggesting that the position of the genetic defect may affect the clinical expression, although this phenotype can occur in mutations throughout the whole PSEN1 gene...

BACKGROUND: The diagnostic construct of mild neurocognitive disorders (MNCDs) is substantially congruent with previously proposed criteria for mild cognitive impairment (MCI). MNCD/MCI is associated with neuropsychiatric symptoms (NPS). Previous studies have examined the prevalence of NPS in amnestic and non-amnestic MCI subtypes; however, no studies exist for etiological types of MNCD. We aimed to estimate the prevalence of NPS in patients with MNCD due to Alzheimer's disease (MNCD-AD) and subcortical vascular MNCD (ScVMNCD) and to determine whether NPS would expand these MNCD phenotypes...

Discovering novel mutations in C9orf72, FUS, ANG, and TDP-43 genes in ALS patients arises necessities for better clinical characterizations of these subjects. The aim is to determine clinical and cognitive profile of genetically positive Serbian ALS patients. 241 ALS patients were included in the study (17 familiar and 224 apparently sporadic). The following genes were analyzed: SOD1, C9orf72, ANG, FUS, and TDP-43. An extensive battery of classic neuropsychological tests was used in 27 ALS patients (22 SOD1 positive and 5 SOD1 negative) and 82 healthy controls (HCs)...

We address this letter in addition to our recent published study (1). The aim is to add some insight to the evolution of the brain abnormalities that are observed with macrophagic myofasciitis (MMF). MMF is a chronic disease whom evolution is slow and symptoms first may occurs from months to year after a vaccination containing aluminium hydroxid adjuvants (2). Nevertheless, its evolution is not fully understood or known. MMF associated cognitive dysfunction (MACD) is based on a tripod combining dysexecutive syndrom, visual memory impairment and interhemispheric disconnection...

BACKGROUND: Accumulating evidence points to the superiority of the MoCA over the MMSE as a cognitive screening tool. To facilitate the transition from the MMSE to the MoCA in clinical and research settings, authors have developed MMSE-MoCA conversion tables. However, it is unknown whether a conversion table generated from Alzheimer's disease (AD) patients would apply to patients with other dementia subtypes like vascular dementia or frontotemporal dementia. Furthermore, the reliability and accuracy of MMSE-MoCA conversion tables has not been properly evaluated...

Studies of executive function and its relationship with brain T2-weighted hyperintensities in children with neurofibromatosis type 1 (NF1) have yielded inconsistent results. We examined 16 children with NF1 aged 8 to 15 years, of normal intelligence, and compared their findings to those of 16 siblings and 16 typically developing children using the Behavioural Assessment of the Dysexecutive Syndrome in Children (BADS-C). NF1 patients had an adequate overall score at BADS-C, but showed significantly lower performance than typical peers in the Key Search subtest...

Alzheimer's disease (AD) and behavioral variant of Frontotemporal Dementia (bvFTD) are characterized respectively by atrophy in the medial temporal lobe with memory loss and prefrontal and anterior temporal degeneration with dysexecutive syndrome. In this study, we hypothesized that specific gait patterns are induced by either frontal or temporal degeneration. To test this hypothesis, we studied the gait pattern in bvFTD (23) and AD (22) patients in single and dual task ("motor" and "cognitive") conditions...

Cognitive impairment is integral to the syndrome of progressive supranuclear palsy. It is most commonly described as a frontal dysexecutive syndrome but other impairments include apathy, impulsivity, visuospatial and memory functions. Cognitive dysfunction may be exacerbated by mood disturbance, medication and communication problems. In this review we advocate an individualized approach to managing cognitive impairment in progressive supranuclear palsy with the education of caregivers as a central component...

A 62-year-old man presented to psychiatric services with a 3-month history of a range of symptoms which included obsessional thoughts, self-neglect, lack of mental flexibility, reduced ability to plan, organise and follow instructions, reduced capacity to empathise and disinhibition. He also accidently set fire to his house. Overall these findings are compatible with a dysexecutive syndrome. This man has a significant history of polysubstance misuse and chronic hepatitis C infection. Neuroimaging revealed an acquired traumatic brain injury which could account for his dysexecutive syndrome...

BACKGROUND AND PURPOSE: Major cognitive disorder (MND) following vascular events is known as second causes of dementia after Alzheimer's disease (AD). Acute onset MND due to isolated hippocampal infarction has not been recognized as a specific subtype of vascular dementia, and there is no validated criteria for the identification of such cases, either clinically or radiologically. RESULTS: Among 7200 patients with first-ever ischemic stroke, 22 patients (0.3%) showed acute isolated ischemic lesions in the hippocampus...

OBJECTIVE: Confabulations are described as "a falsification of memory occurring in clear consciousness in association with an organically derived amnesia". We describe production of confabulations in long-term memory in a 51-year-old woman who do not present amnesic syndrome typically associated. The patient was admitted in reanimation unit for septic shock. After 8 days of coma, she presented signs of encephalopathy of Gayet-Wernicke, without cerebral damage on T1 MRI. OBSERVATIONS: At 6 months of acute episode, the patient presents a severe cognitive and behavioural dysexecutive syndrome, with impulsivity, perseverations and environmental dependency...

It is proposed that depending upon the specific pattern of cognitive abilities, each individual lives in an idiosyncratic "cognitive world." Brain pathology can be associated with some disturbed abilities, and frequently experiential changes (i.e., how the world is understood) are observed. Because these patients often are aware of their intellectual changes, they may represent excellent models to illustrate the diversity of cognitive interpretations an individual can have about the surrounding environmental conditions...

The objectives of this study were to characterize the frequencies and profiles of behavioral and cognitive dysexecutive syndromes in PD (based on validated battery and diagnostic criteria) and to develop a shortened diagnostic battery. Eighty-eight non-demented patients with a diagnosis of PD were examined with an executive validated battery. Using a validated framework, the patients' test results were interpreted with respect to normative data from 780 controls. A dysexecutive syndrome was observed in 80.6% of the patients [95% confidence interval: 71...

REVIEW
E Portaccio
Cognitive impairment is common in multiple sclerosis (MS), affecting up to 70% of patients. One of the most important possible confounders to cognitive assessment is the occurrence of depression, a common consequence of MS. Cognition and depression have been linked in recent neuropsychiatric research that proposed a number of neurocognitive models of mood disorders. According to these models, primary failure of key brain regions of emotional processing and regulation or abnormal connectivity between them contributes to the adoption of maladaptive cognitive strategies and the development of mood disorders...

BACKGROUND: The cognitive status is generally considered as a major determinant of rehabilitation outcome in Parkinson's disease (PD). No studies about the effect of cognitive impairment on motor rehabilitation outcomes in PD have been performed before. OBJECTIVE: This study is aimed to evaluate the impact of cognitive decline on rehabilitation outcomes in patients with PD. METHODS: We retrospectively identified 485 patients with PD hospitalized for a 4-week Multidisciplinary Intensive Rehabilitation Treatment (MIRT) between January 2014 and September 2015...

Schizophrenia is a chronic disabling mental disorder that involves impairments in several cognitive domains, especially in executive functions (EF), as well as impairments in functional performance. This is particularly true in patients with Treatment-Resistant Schizophrenia (TRS). The aim of this study was to test the efficacy of the Occupational Goal Intervention (OGI) method for the improvement of EF in patients with TRS. In this randomized, controlled, single-blind pilot study, 25 TRS patients were randomly assigned to attend 30 sessions of either OGI or craft activities (control) over a 15-week period and evaluated by the Behavioural Assessment of the Dysexecutive Syndrome (BADS) as the primary outcome and the Direct Assessment of Functional Status (DAFS-BR) as well as the Independent Living Skills Survey (ILSS-BR) as secondary outcomes, all adapted for the Brazilian population...
