Olfactory function comes into prominence in the neuroscience study area after revealing that olfactory dysfunction is considered as an early diagnostic pre-motor biomarker of Parkinson’s disease. Researchers have also examined the sense of smell in detail in patients with other neuropsychiatric disorders. Here, we present data from a systematic literature review in olfactory function in child and adult neuropsychiatric disorders. We have researched autism spectrum disorders (ASD), epilepsy, attention-deficit/hyperactivity disorder (ADHD), schizophrenia, bipolar disorder, eating disorders, and obsessive-compulsive disorder (OCD). Due to smell test techniques and heterogeneity of studies, the total number of studies was limited. The disorders were grouped according to smell test techniques. The most commonly-used tests were Sniffin Sticks Test (SST) and the University of Pennsylvania Smell Identification Test (UPSIT). Although some researcher did not find any significant impairment in olfaction, most studies indicated that olfactory dysfunction was very striking, especially in disorders involving in the dopaminergic pathway (e.g., ADHD, autism, and schizophrenia). In this review, possible future diagnostic or prognostic markers of olfactory dysfunction in neuropsychiatric disorders have been discussed. More studies that combine imaging methods, the electrophysiologic system, and genetic research are needed to clarify the relationship between olfaction and neuropsychiatric disorders.

Most of the patients with temporal lobe epilepsy suffer from memory decline following anterior temporal lobectomy (ATL). Studies examining memory decline following ATL show that post operative memory decline can be predicted in advance through the pre operative determination of memory lateralisation. Therefore, preoperative memory lateralisation plays a crucial role for epileptic surgery. Recent research suggests that instead of WADA test which is known as an invasive and high-risk operation, functional MRI can be used as a non-invasive and repeatable method to lateralize memory in the brain and to predict post operative memory decline. The aim of this article is to review the utility of fmri in prediction of post operative memory decline and to summarize the results of recent memory lateralisation studies using fmri.

The Biased Competition Model suggests that stimuli matching the contents of working memory increase the likelihood that memorymatching items will be attended. According to this account, the representations in working memory create an involuntary capture of attention toward memory-matching items in the visual field. This influential assumption proposed by the biased competition model has been explored in a number of studies, showing that the contents of working memory exert an automatic bias in favor of memory matching items. These studies showed that active maintenance of objects in working memory automatically shift attention toward the memory matching-object and produce a negative early lateralized event related potential (ERP), the N2pc, toward the side of visual field where the memorized item appeared. This component, the N2pc is an important tool to investigate the allocation of attention by working memory representations, especially for the activity the activity that is specific to the hemisphere which is contralateral with respect to the hemifield containing e.g. the to-be-remembered items could be measured. This characteristic of the N2pc facilitates measuring the general direction of attention with fine-grained temporal resolution. Therefore, the N2pc could be used as an index to describe the lateralization effect of memorized items on attention related studies.

Communication deficits resulting from aphasia can negatively impact stroke survivors’ social life. It has been reported that patients with severe non-fluent aphasia are better at singing lyrics than speaking the same words. Based on lesion studies, it is generally proposed that the right hemisphere is dominant especially for melody production. We present a 28-year-old woman with non-fluent aphasia as the result of a left hemisphere ischemic stroke involving mainly the superior division of the middle cerebral artery, and classified as having Broca’s aphasia. She was taken into melodic intonation therapy with speech therapy. Singing is accessible and enjoyable for many people with aphasia and melodic intonation therapies may facilitate recovery in such non-fluent aphasic patients.

Objective: To demonstrate the efficacy of EMDR in complex multiple psychological trauma after failed drug treatment from selective serotonin reuptake inhibitor (SSRI) in a diagnosed case of post traumatic stress disorder (PTSD). Material and method: Single participant of this case study, a sitting session judge of judicial governmental scaffold reported to this mental health tertiary care facility at his own accord with features of intense anxiety, depression, maladjustment issues and posttraumatic stress for a duration of several months. As a partial responder to full trial of SSRI he was enrolled for EMDR therapy to address his symptoms of intense anxiety, panic attacks, being overwhelmingly fearful, depressed, low self-esteem, inappropriate feelings of guilt, flashbacks, avoidance, nightmares, hyper-arousal and inability to perform as a judicial head in active war stricken area of northern Pakistan. Complete psychiatric evaluation was carried out and after the discontinuation of SSRIs he was scored on Impact of Event Scale (IES). He fulfilled the diagnostic criteria for PTSD as evaluated by the English version of the PTSD module of the Structured Clinical Interview for DSM-IV administered once before commencement of EMDR. Safe place of the client was established and 8 staged protocol of EMDR was started with him. Multiple EMDR sessions were conducted. Result: The case presented in this paper had multiple psychological trauma forms and failed drug treatment and yet it was observed that EMDR provided marked improvement in all the domains of his deficits and this was at a prompt speed as compared to cognitive behavioural therapy (CBT) which usually takes longer duration of therapy to achieve similar results. Conclusion: EMDR provides marked improvement in all domains of complex mental trauma and traumatic memories. Improvement attained was prompt and enduring as compared to other forms of established therapies and drug treatment indicating permanent changes happening at neurobiological levels of brain.

Sufi meditation is a spiritual form of physically active meditation in which performers (Semazens) whirl without losing conscious awareness and while internally focusing on reaching an ecstatic state, thus requiring substantial motor and cognitive control and monitoring. Studies have argued that the experience of the meditator may affect the strength of the brain activations because more experienced meditators may need less cognitive effort to reach the ecstatic state. Despite this, our knowledge about the associations between emotional states of the meditators and activated brain areas during meditation remains unknown. With this in mind, fourteen male Semazens were recruited for this study. All Semazens performed Sema meditation under the scanner using imagined whirling techniques. An active control condition was used to explore brain areas specific to Sema meditation. Measures of affective states and psychiatric symptoms were also collected. Statistical parametric maps were created to compare the meditation vs. control conditions. Accordingly, Sema meditation specifically evoked activations in left anterior cingulate cortex (ACC) and left orbitofrontal areas. Activations in ACC were negatively correlated with the positive affect of the Semazens suggesting that less cognitive effort required to reach the meditative state in Semazens was associated with more positive affect. Despite previous studies highlighting the experience of the meditators as a predictor of brain activation, we found that affective state may also be an important factor that may facilitate emotion regulation and cognitive monitoring in the brain. Our findings may also be applicable to the effects of meditation on psychological and emotional wellbeing.

Peripheric edema could be caused by various medical conditions as well as pharmacologic agents such as antihypertensives, nonsteroidal antiinflamatory drugs, endocrine agents and immunotherapies. Olanzapine is an atypical antipsychotic that is widely prescribed for the treatment of schizophrenia and bipolar affective disorder. Most common adverse reactions of olanzapine are weight gain, postural hypotension, constipation, dizziness, akathisia, sedation. Peripheral edema was reported as an infrequent side effect, which affected 3% of the olanzapine treated patients. In this report, we aim to draw attention of psychiatrists on this rare adverse effect by presenting a 56-year-old case, who applied to our hospital with severe depressive and obsessive-compulsive symptoms and hospitalized because of suicide risk. Before psychiatric admission, he wasn’t taking any medication. He was diagnosed as major depression with psychotic features and obsessive-compulsive disorder. He was started on olanzapine 10 mg/day, quetiapine 300 mg/day and fluoxetine 40 mg/day. Two weeks after initiation of olanzapine, he was found to have bilateral pedal edema without ulceration and temperature change but minimal redness was observed. He had no history suggestive of cardiac, renal and liver dysfunction or allergic reaction against to any drug that could explain his existing edema. Possible medical conditions which may cause edema were ruled out by laboratory tests and physical examination. Olanzapine was stopped immediately and the therapy was modified to risperidone 1 mg/day. After discontinuation of olanzapine, edema was gradually resolved within two weeks. Because olanzapine associated edema has been seen rarely, it could be overlooked by psychiatrists in comparison to its more common side effects. Although it shows self-limited and benign course, patients may feel discomfort and their compliance to treatment may decrease. Also, it may interfere with differential diagnosis of other medical conditions which may cause edema. In conclusion, we suggest that patients should be observed carefully for edema during olanzapine treatment.
