Delta Vs Gamma Auditory Steady State Synchrony in Schizophrenia.

Background: Delta band (1-4 Hz) neuronal responses support the precision and stability of auditory processing, and a deficit in delta band synchrony may be relevant to auditory domain symptoms in schizophrenia patients.

Methods: Delta band synchronization elicited by a 2.5 Hz auditory steady state response (ASSR) paradigm, along with those from theta (5 Hz), alpha (10 Hz), beta (20 Hz), gamma (40 Hz), and high gamma (80 Hz) frequency ASSR, were compared in 128 patients with schizophrenia, 108 healthy controls, and 55 first-degree relatives (FDR) of patients.

Frontal Glutamate and γ-Aminobutyric Acid Levels and Their Associations With Mismatch Negativity and Digit Sequencing Task Performance in Schizophrenia.

Importance: Auditory mismatch negativity (MMN) is a biomarker for schizophrenia thought to reflect glutamatergic N-methyl-d-aspartate receptor function and excitatory-inhibitory neurotransmission balance. However, the association of glutamate level with MMN has not been directly examined in patients with schizophrenia, to our knowledge.

Objective: To investigate the contributions of glutamate and γ-aminobutyric acid (GABA) to MMN and digit sequencing task (DST) performance, an assessment of verbal working memory, in schizophrenia.

Influence of kynurenine 3-monooxygenase (KMO) gene polymorphism on cognitive function in schizophrenia.

Background: Cognitive deficits compromise quality of life and productivity for individuals with schizophrenia and have no effective treatments. Preclinical data point to the kynurenine pathway of tryptophan metabolism as a potential target for pro-cognitive drug development. We have previously demonstrated association of a kynurenine 3-monooxygenase (KMO) gene variant with reduced KMO gene expression in postmortem schizophrenia cortex, and neurocognitive endophenotypic deficits in a clinical sample.

Long range frontal/posterior phase synchronization during remembered pursuit task is impaired in schizophrenia.

Although smooth pursuit eye movement (SPEM) is a reliable endophenotype of schizophrenia, exact underlying cognitive and neural substrates remain unknown. A simple mechanistic model of SPEM assumes an efficient interaction in integrating sensory input from the medial temporal (MT)/medial superior temporal (MST) brain regions and subsequent motor response through the frontal eye field (FEF). Poor functional connectivity between these two regions could explain impaired motion perception and SPEM maintenance in schizophrenia.

Mitochondrial DNA variations in Madras motor neuron disease.

Although the Madras motor neuron disease (MMND) was found three decades ago, its genetic basis has not been elucidated, so far. The symptom at onset was impaired hearing, upper limb weakness and atrophy. Since some clinical features of MMND overlap with mitochondrial disorders, we analyzed the complete mitochondrial genome of 45 MMND patients and found 396 variations, including 13 disease-associated, 2 mt-tRNA and 33 non-synonymous (16 MT-ND, 10 MT-CO, 3 MT-CYB and 4 MT-ATPase).

The role of social media networks in psychotic disorders: a case report.

We report the case of a young man diagnosed with schizophrenia who presented with stalking behaviors that may have been caused by problematic use or participation in social media networks (SMN). We review the possible role of SMN in the formation of his romantic delusion and offer suggestions for clinicians around incorporation of SMN questions into assessments. It is imperative to identify populations at risk of SMN-related stalking behaviors to stratify mental health resources and interventions.

Tacrolimus-induced paranoid delusions and fugue-like state.

We report the case of a 43 year old male with no prior psychiatric history with apparent tacrolimus-induced psychosis. Previous reports have identified other neurotoxic adverse effects due to tacrolimus, however, to our knowledge, there are few reports that describe psychosis induced by the immunosuppressant drug. Although psychosis may be a rare adverse effect, it can have significant impact on the long-term prognosis and treatment in transplant recipients.

Gender-specific association of TSNAX/DISC1 locus for schizophrenia and bipolar affective disorder in South Indian population.

Genetic association studies have implicated the TSNAX/DISC1 (disrupted in schizophrenia 1) in schizophrenia (SCZ), bipolar affective disorder (BPAD) and major depression. This study was performed to assess the possible involvement of TSNAX/DISC1 locus in the aetiology of BPAD and SCZ in the Southern Indian population. We genotyped seven single nucleotide polymorphism (SNPs) from TSNAX/DISC1 region in 1252 individuals (419 BPAD patients, 408 SCZ patients and 425 controls).

Predictive pursuit association with deficits in working memory in psychosis.

Background: Deficits in smooth pursuit eye movements are an established phenotype for schizophrenia (SZ) and are being investigated as a potential liability marker for bipolar disorder. Although the molecular determinants of this deficit are still unclear, research has verified deficits in predictive pursuit mechanisms in SZ. Because predictive pursuit might depend on the working memory system, we have hypothesized a relationship between the two in healthy control subjects (HC) and SZ and here examine whether it extends to psychotic bipolar disorder (BDP).

Electrophysiological evaluation of spinocerebellar ataxias 1, 2 and 3.

Introduction: Subclinical neuropathy is an important feature of spinocerebellar ataxias (SCA) but the true prevalence and electrophysiological characteristics in genetically proven patients of SCA 1, 2 and 3 are largely unknown.

Methods: We prospectively compared the electrophysiological characteristics of neuropathy in 61 genetically confirmed cases of SCA (SCA1=28, SCA2=16 and SCA3=17). Nerve conduction studies were performed in at least one sensory and one motor nerve, in right upper and lower limb using standard methods.

Gray matter volume deficits in spinocerebellar ataxia: an optimized voxel based morphometric study.

Introduction: Spinocerebellar ataxias (SCA) are a group of autosomal dominant ataxias with varied clinical phenotypes. However there are no unique distinguishing features on routine neuroimaging among the various genetically defined SCAs. Voxel-based morphometry (VBM) provides an automated unbiased analysis of structural MRI scans and gives a comprehensive assessment of anatomical differences throughout the brain.

Madras motor neuron disease (MMND): clinical description and survival pattern of 116 patients from Southern India seen over 36 years (1971-2007).

Madras motor neuron disease (MMND), MMND variant (MMNDV) and Familial MMND (FMMND) have a unique geographic distribution predominantly reported from Southern India. The characteristic features are onset in young, weakness and wasting of limbs, multiple lower cranial nerve palsies and sensorineural hearing loss. We describe the clinical features and survival pattern in 116 patients with Sporadic MMND, MMND variant and FMMND.

SCA 1, SCA 2 & SCA 3/MJD mutations in ataxia syndromes in southern India.

Background & Objective: Spinocerebellar ataxias (SCAs) are often caused by expansions of CTG/ CAG trinucleotide repeat in the genome. Expansions at the SCA1, 2 and 3 loci are the most frequent, but differences in their relative proportion in regions occur across the world. We carried out this study to assess the occurrence of SCA1, 2 and 3, at a tertiary neuro-psychiatric center in Bangalore, Karnataka.
