Psychogenic dystonia is one of the most common problems encountered in movement disorder patients and accounted mostly for misdiagnosis, management confusion and treatment resistance. Psychiatric morbidities often are the culprit, hence proper psychiatric history taking is of utmost importance. Here we report one case where dystonia was the main presenting complaint of an underlying depressive episode and discuss how managing the cause alleviated the symptoms.
Depressive disorder is one of the most common mental health problems currently. However, the mechanism-based treatments for this disorder remain elusive. Repetitive transcranial magnetic stimulation (rTMS), a non-invasive procedure that could stimulate electrical activity by a pulsed magnetic field in the brain, is considered to be an effective treatment for depression. Here, we review the main findings from both clinical and basic research on rTMS for depression, including its antidepressant efficacy, basic principles, as well as its ability to regulate neural circuits, neurotransmitters and brain networks, neurogenesis in hippocampus, and synaptic, and molecular pathways.
Psychogenic seizures are often underdiagnosed and epilepsy is very often over-treated which leads to multiple financial, social and stigma related difficulties. The myoclonic seizure itself is a rare phenomenon and when functional movement disorder presents like myoclonus then it's extremely difficult to pinpoint the exact cause. Here, we are presenting a case who was misdiagnosed as having a myoclonic seizure disorder and treated in multiple places without any improvement which ultimately turned out to be functional movement disorder of a rare variety.
Background: We have developed a structured cognitive behavioral therapy manual for anxiety disorder in China, and the present study evaluated the applicability of simplified cognitive behavioral therapy based on our previous research.
Aims: To evaluate the applicability of simplified cognitive behavioral therapy (SCBT) on generalized anxiety disorder (GAD) by conducting a multi-center controlled clinical trial.
Methods: A multi-center controlled clinical trial of SCBT was conducted on patients with GAD, including institutions specializing in mental health and psychiatry units in general hospitals. The participants were divided into 3 groups: SCBT group, SCBT with medication group and medication group. The drop-out rates of these three groups, the therapy satisfaction of patients who received SCBT and the evaluation of SCBT from therapists were compared.
Results: (1) There was no significant difference among the drop-out rates in the three groups. (2) Only the duration and times of therapy were significantly different between the two groups of patients who received the SCBT, and the therapy satisfaction of the SCBT group was higher than that of the SCBT with medication group. (3) Eighteen therapists who conducted the SCBT indicated that the manual was easy to comprehend and operate, and this therapy could achieve the therapy goals.
Conclusion: The applicability of SCBT for patients with GAD is relatively high, and it is hopeful that SCBT can become a psychological treatment which can be applied in medical institutions of various levels.
Simpson's paradox is very prevalent in many areas. It characterizes the inconsistency between the conditional and marginal interpretations of the data. In this paper, we illustrate through some examples how the Simpson's paradox can happen in continuous, categorical, and time-to-event data.
Background: The incidence of depressive symptoms is higher in cancer patients. And depression can also affect the occurrence, development and outcome of cancer through the neuroendocrine-immune-network system.
Objective: To study the level of Nesfatin-1 in the plasma and brain tissue and its role in the pathogenesis in gastric cancer comorbid with depression using a mouse gastric cancer model.
Methods: 18 mice were randomly divided into the normal control group (NCG), gastric cancer without stress model group (GCNS), and gastric cancer combined with stress model group (GCS). The mice of the GCNS group were inoculated subcutaneously with mouse forestomach carcinoma (MFC) after 5 weeks of nomal feeding to establish a model of subcutaneous transplantation tumor. After 5 weeks of chronic unpredicted mild stress (CUMS) in the GCS group, subcutaneous inoculation of MFC was used to establish a subcutaneous transplantation tumor model for 1 week. Evaluation of mice behavior was performed by open field test, sucrose preference test and forced swimming test (FST). Determination of Nesfatin-1 concentration in plasma and brain tissue was carried out using enzyme linked immunosorbent assay (ELISA) and Western Blot.
Results: The weight increment in the GCS group was significantly lower than that in the GCNS group (t=-3.39, p<0.001). And both GCS and GCNS were lower than the NCG group (t=-6.33, p<0.001; t=-2.94, p=0.01). In the open field test, the horizontal moving distance of the GCS group was less than that of the GCNS group (t=-2.50, p=0.025), and both GCS and GCNS were smaller than the NCG group (t=-5.87, p<0.001; t=-3.38, p=0.004). The dead time of the GCS group was longer than that of the GCNS and the NCG groups (t=2.56, p=0.022; t=3.84, p=0.002). The Nesfatin-1 level in the middle brain, hippocampus and plasma was significantly higher in NCG group and GCS group than in the GCNS group. The concentration of Nesfatin-1 in the GCS group was significantly higher than that in the NCG group.
Conclusions: There is a decrease of Nesfatin-1 level in brain tissue and plasma in mice with gastric cancer without stress. CUMS stress can induce depressive behavior in gastric cancer mice, and increase the level of Nesfatin-1 in brain tissue and plasma. Therefore, Nesfatin-1 may be related to the pathogenesis of gastric cancer stress related depression.
Little is known internationally about the psychiatric epidemiology and mental health services in Tibet. This article reviews the relevant research of psychiatric epidemiology and mental health services in the Tibet Autonomous Region (TAR), P. R. China. There is a substantive number of people suffering from mental disorders and psychological problems in an area with a general lack of modern mental health institutions and professionals.
Background: Bipolar disorder is a mental illness with a high misdiagnosis rate and commonly misdiagnosed as other mental disorders including depression, schizophrenia, anxiety disorders, obsessive-compulsive disorders, and personality disorders, resulting in the mistreatment of clinical symptoms and increasing of recurrent episodes.
Aims: To understand the reasons for misdiagnosis of bipolar disorder in an outpatient setting in order to help clinicians more clearly identify the disease and avoid diagnostic errors.
Methods: Data from an outpatient clinic included two groups: those with a confirmed diagnosis of bipolar disorder (CD group) and those who were misdiagnosed (i.e. those who did in fact have bipolar disorder but received a different diagnoses and those without bipolar disorder who received a bipolar diagnosis [MD group]). Information between these two groups was compared.
Results: There were a total of 177 cases that met the inclusion criteria for this study. Among them, 136 cases (76.8%) were in the MD group and 41 cases (23.2%) were in the CD group. Patents with depression had the most cases of misdiagnosis (70.6%). The first episode of the patients in the MD group was more likely to be a depressive episode (χ2=5.206, p=0.023) and these patients had a greater number of depressive episodes during the course of the disease (Z=-2.268, p=0.023); the time from the onset of the disease to the first treatment was comparatively short (Z=-2.612, p=0.009) in the group with misdiagnosis; the time from the onset of disease to a confirmed diagnosis was longer (Z=-3.685, p<0.001); the overall course of disease was longer (Z=-3.274, p=0.001); there were more inpatients for treatment (χ2=4.539, p=0.033); and hospitalization was more frequent (Z=-2.164, p=0.031). The group with misdiagnosis had more psychotic symptoms (χ2=11.74, p= 0.001); particularly when depression occurred (χ2=7.63, p= 0.006), and the incidence of comorbidity was higher (χ2=5.23, p=0.022). The HCL-32 rating was lower in the misdiagnosis group (t=-2.564, p=0.011). There were more patients diagnosed with bipolar and other related disorders in the misdiagnosis group than in the confirmed diagnosis group (11.0% v. 4.9%) and there were more patients in the MD group diagnosed with depressive episodes who had a recent episode (78.7% v. 65.9%).
Conclusions: The rate of misdiagnosis of patients with bipolar receiving outpatient treatment was quite high and they often received a misdiagnosis of depression. In the misdiagnosis group the first episode tended to manifest as a depressive episode. In this group there were also a greater number of depressive episodes over the course of illness, accompanied by more ps
