To better understand the natural history of poststroke apathy, the authors tested 96 patients undergoing acute rehabilitation for stroke using the Apathy Inventory. A total of 28% of patients had apathy. Their Apathy Inventory scores improved a mean of 1 point by week 2 and 2 points by week 3, with the majority of patients remaining apathetic at discharge. Apathy severity correlated with aphasia, weakness, and impaired cognition but did not correlate with depression. These findings suggest that acute rehabilitation is an optimal setting for clinical trials for poststroke apathy, because apathy is associated with poor outcomes and shows only a small degree of spontaneous improvement.

A clinicopathological investigation was conducted on a case of an 89-year-old man with a 10-year history of progressive dementia who also suffered strokes, apathy, aphasia, dysarthria, weakness of both legs, and walking difficulties. At autopsy, we found an obvious atrophy of the frontal and temporal cortex. Lewy bodies (LBs) could be seen in brain stem, amygdala, and neocortex. Argyrophilic grains were observed in hippocampus, entorhinal cortex, neocortex, amygdala, and pons, as well as neurofibrillary tangles in the entorhinal cortex and hippocampus. The case presented here is a rare case of frontotemporal lobar degeneration with accumulation of argyrophilic grains and Lewy bodies.

Vitamin B12 is one of the essential vitamins affecting various systems of the body. Vitamin B12 deficiency in infants often produces haematological and neurological deficits including macrocyticanaemia, neurodevelopmental delay or regression, irritability, weakness, hypotonia, ataxia, apathy, tremor andseizures. In this article, we report the case of a six-month-old male patient diagnosed with West syndrome associated with vitamin B12 deficiency. Although the patient had no evidence of macrocytic anemia in complete blood count, we measured the level of vitamin B12 because the patient had hypotonicity and found it to be low. No other problem was found in the other investigations directed to the etiology of West syndrome. He was being exclusively breast-fed and vitamin B12 deficiency was related with nutritional inadequacy of his mother. Vitamin B12 deficiency should be considered in the differential diagnosis of patients presenting with different neurological findings. In addition, vitamin B12 deficiency should be considered as a rare cause in West syndrome which has a heterogeneous etiology.

This study describes cryptosporidiosis in an overwintering group of 15 European hedgehogs (Erinaceus europaeus), comprising 3 adults and 12 juveniles. Four juvenile hedgehogs were hospitalised with anorexia, malodorous diarrhoea and dehydration. Immediate parasitological examinations revealed the presence of Cryptosporidium sp. in these animals and also in 5 other juveniles. All hedgehogs were coproscopically monitored for 4 months over the winter season. Shedding of Cryptosporidium oocysts persisted from 6 to 70 days. Repeated shedding of Cryptosporidium oocysts occurred in 3 animals after 4 months subsequent to the first outbreak. Clinical signs were observed only at the beginning of the outbreak (apathy, anorexia, general weakness, mild dehydration, and malodorous faeces with changed consistence - soft/diarrhoea) in the 4 hospitalised juveniles. Overall 11 hedgehogs were Cryptosporidium-positive, both microscopically and by PCR methods. Sequence analyses of SSU rRNA and gp60 genes revealed the presence of C. parvum IIdA18G1 subtype in all positive hedgehogs. Moreover, 3 hedgehogs had a mixed infection of the zoonotic C. parvum and C. erinacei XIIIaA19R13 subtype. Cryptosporidium infections can be rapidly spread among debilitated animals and the positive hedgehogs released back into the wild can be a source of the infection for individuals weakened after hibernation.

We report an autopsy case of globular glial tauopathy (GGT) presenting clinically with amyotrophic lateral sclerosis (ALS) with dementia. A 79-year-old female developed weakness in the right upper limb, which progressed gradually. She developed apathy and speech disorder at 80 years of age. On neurological examination, she showed signs of upper and lower motor neuron disorder and dementia, but no extrapyramidal signs. The clinical diagnosis was ALS with dementia. The autopsy revealed left predominant marked atrophy of the frontal lobe due to severe neuronal loss and Gliosis. Immunohistochemistry using anti-4-repeat tau antibody revealed numerous globular glial inclusions. Severe neurodegeneration in the primary motor cortex and corticospinal tract was observed. There were distinctive tau-positive inclusions in both Betz and anterior horn cells. TDP-43-positive inclusions in motor neurons were not detected. Sequence analysis of the tau gene revealed no mutations in exons 1-5, 7, 9-13, or the adjacent intronic sequences. GGT can cause a clinical phenotype of ALS with dementia.

A 19-year-old man presented with a 1-year history of headache, generalised body weakness, progressive memory loss, and disorientation. One month prior to admission, there was aggravation of the weakness of the right upper limb, with new-onset difficulty with mastication, speech impairment, apathy, and urinary incontinence. On clinical examination, the patient had a motor aphasia and a right-sided hemiparesis with increased muscle tone and hyperreflexia. A noncontrast computed tomography (CT) scan of the brain revealed large ischaemic strokes extending beyond the classical vascular territories. Cerebrospinal fluid analysis showed a mildly increased protein level. The electrocardiogram revealed an irregular sinus bradycardia. The remainder of the cardiovascular and laboratory workup was unremarkable. Considering a working diagnosis of central nervous system vasculitis, the patient was treated with aspirin, prednisolone, and physiotherapy. However, he died suddenly a few weeks later. Based on this case, we discuss the challenges of stroke management in resource-limited settings, provide practical tips for general practitioners, reflect on the potential avenues for short- and long-term action, and introduce the budding collaboration platform between the University College London, the University of Liverpool, the Queen Elizabeth Central Hospital, and the Malawi-Liverpool-Wellcome Trust Clinical Research Programme.

Movement disorders can be defined as neurological syndromes presenting with excessive or diminished automatic or voluntary movements not related to weakness or spasticity. Both Parkinson's disease (PD) and Huntington's disease (HD) are well-known examples of these syndromes. The high prevalence of comorbid psychiatric symptoms like depression, anxiety, obsessive-compulsive symptoms, hallucinations, delusions, impulsivity, sleep disorders, apathy and cognitive impairment mean that these conditions must be regarded as neuropsychiatric diseases. In this article, we review neuroanatomical (structural and functional), psychopathological and neuropsychological aspects of PD and HD. The role of fronto-subcortical loops in non-motor functions is particularly emphasised in order to understand the clinical spectrum of both diseases, together with the influence of genetic, psychological and psychosocial aspects. A brief description of the main psychopharmacological approaches for both diseases is also included.

Porcine circovirus type 2 (PCV2) is associated with multiple clinical syndromes in pigs, known as porcine circovirus diseases. This work describes an outbreak of porcine circovirus diseases with severe lesions affecting the skeletal muscle. Ninety-two pigs had apathy, weight loss, and diarrhea over a clinical course of 7 to 10 days. Approximately 30 of the pigs had stiff gait, muscle weakness, hind limb paresis, and recumbency. Twelve of the 92 pigs were necropsied, and 4 had pale discoloration of skeletal muscles with microscopic lesions of granulomatous necrotizing myositis. Immunohistochemistry of skeletal muscle showed that PCV2 antigen was located primarily in the cytoplasm and nuclei of macrophages, lymphocytes, and multinucleated giant cells, with a lower amount in the cytoplasm of endothelial cells, necrotic fibers, and satellite cells. Affected muscle samples were polymerase chain reaction-positive for PCV2 and the amplicon exhibited 99% identity with sequences belonging to the PCV2b genotype. Locomotor clinical signs and granulomatous necrotizing myositis should be considered as another expression of PCV2 infection in pigs.

Delays in diagnosis due to low Breast Cancer awareness are widespread in Brazil maybe owing to ineffective strategies to raise attention on early diagnosis. As a proxy of collective interest in BC screanning (BCS) we studied the monthly accesses to BC and BCS webpages in INCA's website along 48 months. A log analyzer built a time serie (2006-2009) of BC and BCS monthly means, which oscilations were studied by analysis of variance (ANOVA). We found significant increasing accesses to BC and transient "attention peaks". Enlargement in BC/BCS differences along all period were caused by increasing accesses to BC and decreasing/minor/stable oscillations to SBC pages. These results are consistent with previous reports on increasing interest to BC contrasting with indifference on BCS. In the context of an exploratory study, we discussed some aspects: weakness of a "prevention culture"; lack of confidence in health system and screening programs; "celebrity effect" in the context of media framing; collective perception of risks heightened by perception of social vulnerability. Findings suggest that culture-tailored communication strategies would be necessary to inform Brazilian people about BCS. Future research is needed to study social perceptions and constructions on BC topics.

VCP-proteinopathy is a multisystem neurodegenerative disorder caused by mutations in valosin containing protein. Here, we report the first Greek case of VCP-proteinopathy in a 62 year old patient with a slowly progressing muscular weakness since his mid-40s and a severe deterioration during the last year. He also manifested dementia with prominent neuropsychiatric symptoms, including aggression, apathy, palilalia and obsessions. Brain MRI revealed frontal atrophy, while muscle MRI showed diffuse muscle atrophy. Family history was positive and several members of the family had been diagnosed with motor neuron disease, dementia or behavioral symptoms. Sequencing of the VCP gene revealed a pathogenic heterozygous missense mutation p.R159H. Conclusively, the present report highlights the intrafamilial variability and broadens the phenotypic spectrum of VCP-proteinopathy.
