Right hippocampal volume and volume change did not predict subsequent anxiety scores or anxiety change scores. However, a new comprehensive study published in Molecular Psychiatry proves that the relationship is reversed: recurrent depression causes brain damage. Quantitative and qualitative methods of assessing the medial temporal lobe were also compared. Eight of the 10 depressed subjects were receiving antidepressants: selective serotonin reuptake inhibitors in three cases, tricyclic antide- pressantsinthreecases, andmaprotilineandtrazodonein one The neurocognitive consequences of hippocampal atrophy have largely been described (22–24), whereas less is known about the link between hippocampal atrophy and depressive symptoms. We further evaluate our method using simulations and provide theoretical guarantees. The medial temporal lobe atrophy (MTA) score is useful in distinguishing patients with mild cognitive impairment and Alzheimer disease from those without impairment 2 is helpful in the assessment of patients with possible dementia (see neurodegenerative MRI brain - an approach).. In AD, atrophy is due primarily to loss of neurons and neuronal volume as a result of neurofibrillary tangle formation. While hippocampal atrophy is a key feature of both hippocampal sclerosis (HS) and Alzheimer's disease (AD), the pathology underlying this finding differs in these two conditions. Methods: We included 64 patients with AD (67 ± 9 years; F/M 38/26), 44 patients with MCI (71 ± 6 years; 21/23), and 34 controls (67 ± 9 years; 16/18).
Damage to the hippocampus may occur in a number of different ways. Natl. Using RAM, a relatively new approach to hippocampal structural analysis, we found that patients with a history of FS, and BDI-II ≥14, had evidence for atrophy contralateral as well as ipsilateral to the seizure focus, suggesting that both FS and depressive symptoms have widespread effects. To complicate MRI interpretation, atypical findings of AD may include little or no hippocampal atrophy and focal asymmetric cortical atrophy. This study was conducted to explore hippocampal structural changes and their possible associations with clinical characteristics, emotional status, and treatment regimens in patients with systemic lupus erythematosus (SLE) without major neuropsychiatric manifestations (non-NPSLE). 2 The neurocognitive consequences of hippocampal atrophy have largely been described (22–24), whereas less is known about the link between hippocampal atrophy and depressive symptoms. Proc. In conclusion, we found that the early hippocampal atrophy could occur before obvious neuropsychiatric manifestations and might be associated with SLE disease activity and organ damages. The study suggests the following hypothesis: the small size of the hippocampus in patients with 22q11 deletion syndrome is defined in the mother’s womb, probably due to poor vascularisation. Atrophy in the left superior frontal gyrus and right lingual gyrus developed in parallel with depressive symptoms, and in the left temporal pole, superior temporal cortex, and supramarginal cortex after the onset of depressive symptom. that atrophy of CA1 and subiculum subregions may cause more severe behavioral deficits compared to CA2 and CA3 subregions. Sci. Objective: To investigate the added value of hippocampal atrophy rates over whole brain volume measurements on MRI in patients with Alzheimer disease (AD), patients with mild cognitive impairment (MCI), and controls. One common way this area of the brain is damaged is through Alzheimer's disease, which often affects the hippocampus early in the progression of the disease. Higher Anxiety Symptoms Predict Progressive Hippocampal Atrophy in the Chronic Stages of Moderate to Severe Traumatic Brain Injury Alex R. Terpstra, MSc , Todd A. Girard, PhD , Brenda Colella, MA , and Robin E. A. Scientists have correlated atrophy (shrinkage) of the hippocampal areas with the presence of Alzheimer's disease. Conclusions. Early detection and intervention of hippocampal damage might prevent the progression to NPSLE. 5), and … And since the 1950s, with the advent of the first generation of antidepressants, it has been apparent that depression is a biological disorder. For years researchers have thought that brain damage, specifically shrinkage of the hippocampus, causes depression. However, a “second hit” later in development might determine the further hippocampal atrophy and the emergence of psychotic symptoms.
