Impairments in cognitive functions and emotional and social behaviors in a rat lithium-pilocarpine model of temporal lobe epilepsy.

Impairments in cognitive functions and emotional and social behaviors in a rat lithium-pilocarpine model of temporal lobe epilepsy. Behav Brain Res. 2019 Jun 17;:112044 Authors: Smolensky IV, Zubareva OE, Kalemenev SV, Lavrentyeva VV, Dyomina AV, Karepanov AA, Zaitsev AV Abstract The aim of this study was to evaluate in detail behavioral patterns and comorbid disturbances in rats using the lithium-pilocarpine model. A comprehensive set of behavioral tests was used to investigate behavioral patterns, including the open field test, Morris water maze, Y-maze, fear conditioning, the elevated plus maze, the forced swimming test, and the resident-intruder paradigm. Motor and explorative activity, learning and memory, anxiety and depressive-like behavior, aggression, and communication were evaluated 8-15 d after pilocarpine-induced status epilepticus (SE) (latent phase of the model) and 41-53 d (chronic phase) after pilocarpine-induced SE. Increased motor activity and impaired memory function were the most noticeable behavioral modifications in the epileptic rats. Both the movement speed and distance traveled increased in the open field test in both the latent and chronic phases. Significant impairments were detected in short-and long-term spatial memory in the Morris water maze during the latent phase. Besides the alterations in spatial memory, behaviors indicative of short- and long-term fear-associated memory disturbances were observed in the fear conditioni...

Conclusion: Some patients with psychiatric syndromes and increased ANA titers may suffer from psychiatric variants of SLE, even if the American College of Rheumatology criteria for SLE are not met. Whether the psychiatric symptoms in our patient represent a prodromal stage with the later manifestation of full-blown SLE or a subtype of SLE with isolated CNS involvement remains unclear. Regardless, early diagnosis and initiation of immunosuppressive treatment are essential steps in preventing further disease progression and organ damage. Intrathecal ANAs with extractable nuclear antigen differentiation may be a more sensitiv...

In this study, we compared the dynamic resting-state local and large-scale FC between PTSD patients (n = 22) and healthy controls (HC; n = 22; conducted as standard deviation in resting-state local and large-scale FC over a series of sliding windows). Local dynamic FC was examined by calculating the dynamic regional homogeneity (dReHo), and large-scale dynamic FC (dFC) was investigated between regions with significant dReHo group differences. For the PTSD patients, we also investigated the relationship between symptom severity and dFC/dReHo. Our results showed that PTSD patients were characterized by I) increased dynamic (...

Marcia H. Ratner, Vidhya Kumaresan and David H. Farb* Laboratory of Molecular Neurobiology, Department of Pharmacology and Experimental Therapeutics, Boston University School of Medicine, Boston, MA, United States Memory dysfunction is a symptomatic feature of many neurologic and neuropsychiatric disorders; however, the basic underlying mechanisms of memory and altered states of circuitry function associated with disorders of memory remain a vast unexplored territory. The initial discovery of endogenous neurosteroids triggered a quest to elucidate their role as neuromodulators in normal and diseased brain functio...

ConclusionCompared with girls in the general population, girls with epilepsy seem to be at a higher risk of being diagnosed with ADHD/ASD as the gender ratio is more equal. This could be related to differences in the assessment of CWE and/or a shared pathogenesis between psychiatric conditions and epilepsy.

CONCLUSION: Compared with girls in the general population, girls with epilepsy seem to be at a higher risk of being diagnosed with ADHD/ASD as the gender ratio is more equal.

In conclusion, the studies presented in the current review demonstrate that CBD has the potential to limit delta-9-THC-induced cognitive impairment and improve cognitive function in various pathological conditions. Human studies suggest that CBD may have a protective role in delta-9-THC-induced cognitive impairments; however, there is limited human evidence for CBD treatment effects in pathological states (e.g. schizophrenia). In short, they found that CBD may help alleviate the negative impact of a person with schizophrenia from taking cannabis, both in the psychotic and cognitive symptoms associated with schizophrenia. T...

Authors: Danek M, Danek J, Araszkiewicz A Abstract Many animal models in different species have been developed for mental and behavioral disorders. This review presents large animals (dog, ovine, swine, horse) as potential models of this disorders. The article was based on the researches that were published in the peer-reviewed journals. Aliterature research was carried out using the PubMed database. The above issues were discussed in the several problem groups in accordance with the WHO International Statistical Classification of Diseases and Related Health Problems 10thRevision (ICD-10), in particular regarding: ...

Conclusion Epilepsy is associated with a poor psychiatric status and HRQL in childhood. The impact of epilepsy on the HRQL occurs mainly through child-related psychiatric factors. Both the child-reported and parent-reported questionnaires seem to be useful for the evaluation of the HRQL in pediatric epilepsy cases.

CONCLUSION: Our results suggest that idiopathic epilepsy may be accompanied by various neuropsychological comorbidities even at initial diagnosis. Patients with IGE and ILRE having bilateral IEDs on EEG appear more likely to be at high risk of decreased cognitive function. PMID: 29215804 [PubMed - in process]
