The aim of the present study was to detect TL, human telomerase reverse transcriptase (hTERT), and brain derived neurotrophic factor (BDNF) in severe mania and subsequent remission.
Sixty-six subjects with BD (41 in manic and 25 in depressive episodes) and 78 healthy volunteers were genotyped for BDNFVal(66)Met and tested for creativity using the Barrow Welsh Art Scale (BWAS) and neuropsychological tests.
The present study aimed to evaluate the effects of treatment with lithium (Li) and valproate (VPA) on behaviors and brain BDNF, NGF, NT-3, NT-4 and GDNF levels in mice submitted to paradoxical sleep deprivation (PSD), which induces an animal model of mania.
This study not only assessed the association between the 5-HTTLPR and BPD with accumulating relevant studies, but also in the first time evaluated the effect of the 5-HTTLPR on both anti-depressive and anti-manic treatment responses in bipolar patients.
The association analysis performed showed a significantly higher rate of homozygous s/s genotype for 5-HTTLPR among patients with a history of antidepressant-induced mania (60% patients s/s versus 40% l/l, chi, P=0.04).
In mood disorder patients, the level of mania (in both acute and stabilized periods) and depression in stabilized periods was positively associated with GSK3Brs12630592 T only in FXR1 rs496250 A-allele carriers (Bonferroni-corrected interaction p=0.024, 0.052 and 0.017 respectively).
Several currently available animal models reproduce select behavioral facets of human mania as well as the abnormal glutamatergic neurotransmission and dysregulation of glycogen synthase kinase 3β that accompanies this disease.
We observed a significant association between homozygosis for the rs4680COMT low-activity variant and a reduced recurrence of manic, but not depressive, episodes during the course of the illness.
This study aimed to test whether a history of manic/hypomanic irritability is associated with low serum progesterone levels; and whether single nucleotide polymorphisms (SNPs) in gene coding for steroidogenetic enzymes (HSD3B2, SRD5A1 and AKR1C4 were coupled to previous manic irritability and/or with serum progesterone concentrations.
Polymorphisms of the GR-gene are factors which influence some clinical manifestations of BD, with respect to seasonal pattern of (hypo)mania and age of onset.
Patients undergoing mania and mixed episodes carrying the COMT allele G had better performance on executive function, memory, verbal fluency, and intelligence tests.
Shank3, a postsynaptic scaffolding protein involved in regulating excitatory synapse assembly and function, has been implicated in several brain disorders, including autism spectrum disorders (ASD), Phelan-McDermid syndrome, schizophrenia, intellectual disability, and mania.
