Bipolar disorderalso known as manic depression, is a mental health disorder that causes extreme mood swings that include emotional highs mania or hypomania and lows depression. It is characterized by major mood swings from mania to depression. This illness can be difficult to manage, but there are many effective treatments. The goal of treatment is to prevent relapse and recurrence, as the recurrent nature of the disorder can be destabilizing for those affected. The term " bipolar disorder " is relatively new, dating back toand refers to a disturbance in mood mechanisms. People with bipolar disorder may experience alternating phases of elation and depression. Mania is characterized by elevated mood, increased energy, rapid thinking, impulsivity and risky behaviour. Hypomania is a milder form of mania, but it can still cause significant problems in social, professional and personal relationships. Biomarkers are biological measures that can be used to help diagnose the illness and track its progression. Some potential biomarkers for bipolar disorder include:. Neurotransmitter levels : Levels of certain neurotransmitters, such as dopamine and serotonin, may be different in people with bipolar disorder. Studies have shown that dating someone with manic depression levels are higher during manic episodes, while serotonin levels are lower during depressive episodes. Inflammatory dating someone with manic depression : Studies have shown that inflammatory markers, such as C-reactive protein CRP and cytokines, can be elevated in people with bipolar disorder. This suggests that inflammation may play a role in the development of the illness. Genetic biomarkers : Studies have identified several genes that may be involved in the development of bipolar disorder. Mutations in these genes may increase the risk of developing the disorder. Brain imaging biomarkers : Brain imaging, such as MRI and PET scans, can be used to measure brain structure and activity in people with bipolar disorder. Studies have shown that people with bipolar disorder have differences in brain structure and activity compared to people without the disorder.
DA mainly acts onto D1 and D2 receptor subtypes, which are positively and negatively coupled to ADCYs [ 73 ]. Genome-wide association study reveals two new risk loci for bipolar disorder. Despite the conservative nature of this substitution, functional consequences, e. Directions Patient Admission Patient Discharge Stay » Zur Übersicht Food Supply for Patients Lost and Found.

Introduction
This relationship, however. Objective: Research in adults has identified an association between bipolar disorder and suicidal behavior. Bipolar affective disorder is a serious mood disorder characterized by manic and depressive mood swings. Exposure to chronic social defeat stress switches homozygous Leu variant carriers from a mania- to a depressive-like state, a transition which. It is argued that among studies that were published within recent decades to this. Compares development within the fields of medical genetics and psychiatry.Besides confirming the introduced ValLeu mutation on the genomic DNA level, we substantiated equal expression levels of Ady2-WT and Adcy2-L mRNA in WT and L mice Fig. Differentially expressed genes particularly identified from glutamatergic CA1 neurons point towards ADCY2 variant-dependent alterations in multiple biological processes including cAMP-related signaling pathways. Article PubMed Google Scholar Griebel G, Holsboer F. However, current technical obstacles prevent a specific assessment in tissues or cells derived from Adcy2 VL mice. To analyze the biological relevance of discovered genes, we chose the cell types with at least 10 DEGs Fig. The lecture by Professor von Haebler will be in German. The genetics of bipolar disorder. EB, JPL and AC supervised and executed the single cell experiment including the data analysis. Ostrom RS, Bogard AS, Gros R, Feldman RD. This serves as a criterion to distinguishing them from natural mood swings. Kim EY, Miklowitz DJ, Biuckians A, Mullen K.

The goal of treatment is to prevent relapse and recurrence, as the recurrent nature of the disorder can be destabilizing for those affected. Sen, P. Hence, it encodes a missense mutation resulting in a Val to Leu substitution at position ValLeu within the 4 th transmembrane helix of the first transmembrane domain Fig. A genome-wide association study implicates diacylglycerol kinase eta DGKH and several other genes in the etiology of bipolar disorder. Among these loci, the adenylyl cyclase 2 gene ADCY2 has been identified as a potential risk gene for BD [ 14 ], a finding which has been replicated by the latest, and to date largest, BD GWAS meta-analyses [ 15 , 16 ].

Seen from a psychodynamic perspective, the patients often have great difficulty processing insults, disappointments and sometimes also successes in adequate ways.
