Background and Objective: Ethanol and nicotine increase dopamine release in different parts of the brain such as the nucleus accumbens and the hippocampus. Dopamine D1 receptors have been detected in dorsal hippocampus known as a key brain region that seems to mediate some behavioral effect of ethanol and nicotine. The present study was carried out to determine the influence of dopamine D1 rece...
Objects: Different theories were suggested on the etiopathogenesis of transient global amnesia. Methods: We demonstrate a patient with transient global amnesia, in whom, a transient hyperintense signal change on left hippocampus was detected in diffusionand T2weighted magnetic resonance images. Conclusion: The absence of vascular risk factors or atherosclerotic changes in neuroimaging, in addit...
conclusions analysis of codeine to morphine metabolism rate is needed when we are using morphine/codeine ratio to rule out abuse of narcotics. wada should consider analysis for the cyp2d6 alleles (main metabolizer of codeine) in case of including morphine/codeine ratio in future prohibited list. the possibility of ultra-rapid cyp2d6 cannot be ruled out in certain results of morphine/codeine nea...
OBJECTIVE The current study examines the demographics, injury characteristics, and outcomes associated with the presence of postconcussion amnesia in young concussion clinic patients. DESIGN Cross-sectional, retrospective clinical cohort. SETTING Concussion services clinic. PATIENTS Pediatric and adolescent concussion services program patients, presenting within 10 days postinjury, aged 1...
A 57-year-old woman developed severe generalised amnesia following an embolic stroke. The amnesia persisted until her death nine months later. The left hemisphere had a large infarction of the medial temporal-occipital region, while the right showed only a small infarct limited to the posterior two-thirds of the hippocampus. If bilateral lesions are necessary for the production of permanent amn...
Background and Objective: Nitric oxide mediated some behavioral effects of nicotine and ethanol in the nucleus accumbens. In the present study, the effects of L-NAME (nitric oxide synthase inhibitor) in the nucleus accumbens on nicotine’s effect in ethanol-induced amnesia were investigated. Materials and Methods: In this experimental study 96 adult male wistar rats were used (12 groups)...
This case study describes post-traumatic stress disorder (PTSD) and head injury after a road traffic accident involving a pedestrian. Previous studies have proposed two mechanisms by which this dual diagnosis may occur: (1) when post-traumatic amnesia and retrograde amnesia are small or non-existent and (2) when non-declarative memory systems for the traumatic event are in operation. This case ...
Transient global amnesia (TGA) is a temporary amnestic syndrome characterized by anterograde amnesia and variable retrograde amnesia without other focal neurological deficits. Neuropsychological tests during attack in TGA have been rarely reported. We report a 62-year-old man with TGA who was evaluated with detailed neuropsychological tests during attack. Ictal neuropsychological tests showed e...
INTRODUCTION Transient global amnesia is a classical disease. It presents with an abrupt onset of anterograde amnesia. It's incidence and recurrence rate is low. CASE PRESENTATION In this case report a 54-year old white male is presented with two attacks of loss of memory within a year. CONCLUSION Recurrent transient global amnesia is rare. Recognition and explaining the good nature of the ...
