Maternal separation and poor maternal care in animals have been shown to have important effects on the developing hippocampus and amygdala.
-
Alzheimer disease-specific cortical thinning and hippocampal volume loss are consistent with a sigmoidal pattern, with an acceleration phase during the early stages of the disease.
-
Hippocampal volume loss in first episode depression is consistent with a neurodevelopmental model of depression, advocating hippocampal structure as a potential diagnostic neurobiomarker for depression.
-
The meta-analyses revealed structural brain abnormalities in MDD that are distinct from those observed in BD.
-
The hippocampal formation plays an important role in cognition, spatial navigation, learning, and memory.
-
Metabolic dysregulation, especially insulin resistance, was associated with lower brain volumes and executive function in a large, relatively healthy, middle-aged, community-based cohort.
-
Biological changes activated by stress represent a significant factor influencing brain structure and function in first-episode psychosis through an effect on BDNF.
-
Hippocampal volume reductions and functional impairments are reliable findings in posttraumatic stress disorder (PTSD) imaging studies.
-
64/100
Several magnetic resonance imaging studies have reported hippocampal volume reduction in patients with schizophrenia, but other studies have reported contrasting results.
-
Chronic restraint stress (CRS) induces the remodeling (i.e., retraction and simplification) of the apical dendrites of hippocampal CA3 pyramidal neurons in rats, suggesting that intrahippocampal connectivity can be affected by a prolonged stressful challenge.
-
The hippocampus shrinks in late adulthood, leading to impaired memory and increased risk for dementia.
-
60/100
The hippocampus is involved at the onset of the neuropathological pathways leading to Alzheimer's disease (AD).
-
The current study suggests that the degree of HPA hyperactivity can vary considerably across patient groups.
-
Recent neuroimaging studies proposed the importance of the anterior auditory pathway for speech comprehension.
-
Lower volume in the right hippocampus in chronic cannabis users was corroborated.
-
The main aim of the present study was to compare volume differences in the hippocampus and parahippocampal gyrus as biomarkers of Alzheimer's disease (AD).
-
The study of patients with semantic dementia, a variant of frontotemporal lobar degeneration, has emerged over the last two decades as an important lesion model for studying human semantic memory.
-
We applied an automated hippocampal segmentation technique based on adaptive boosting (AdaBoost) to the 1.5 T magnetic resonance imaging (MRI) baseline and 1-year follow-up data of 243 subjects with mild cognitive impairment (MCI), 96 with Alzheimer's disease (AD), and 145 normal controls (NC) scanned as part of the Alzheimer's Disease Neuroimaging Initiative (ADNI).
-
The patterns of subfield atrophy in AD and MCI were consistent with patterns of neuronal cell loss/reduced synaptic density described by histopathology.
-
Our results suggest that decreased hippocampal tail and hippocampal head volumes could be trait changes, whereas hippocampal body changes may be dependent on treatment.
-
Because children are becoming overweight, unhealthy, and unfit, understanding the neurocognitive benefits of an active lifestyle in childhood has important public health and educational implications.
-
Neurogenesis in the hippocampus occurs throughout life in a wide range of species and could be associated with hippocampus-dependent learning and memory.
-
Trauma exposure itself in the absence of posttraumatic stress disorder (PTSD) may be associated with hippocampal volume deficits.
-
We propose a nonparametric, probabilistic model for the automatic segmentation of medical images, given a training set of images and corresponding label maps.
-
Cerebrospinal fluid (CSF) measures of Ab and tau, Pittsburgh Compound B (PIB) imaging and hippocampal atrophy are promising Alzheimer's disease biomarkers yet the associations between them are not known.
-
The abnormal enlargement of the amygdala and hippocampus in adolescents with autism adds to previous findings of enlargement of these structures in children with autism.
-
Longitudinal fMRI provides a reliable indicator of brain activation over time, and may prove useful in identifying functional brain changes associated with cognitive decline on the trajectory toward clinical Alzheimer disease.
-
Compared with healthy controls, adults with SCA had poorer cognitive performance, which was associated with anemia and age.
-
We propose a new method of measuring atrophy of brain structures by simultaneously segmenting longitudinal magnetic resonance (MR) images.
-
With the increased interest in the use of sequential magnetic resonance images as potential surrogate biomarkers of the disease process, it has also been shown that the rate of hippocampal atrophy is higher in persons with Alzheimer's disease compared to those with mild cognitive impairment and the healthy elderly.
-
50/100
Hippocampal volume shrinks in late adulthood, but the neuromolecular factors that trigger hippocampal decay in aging humans remains a matter of speculation.
-
Volume and change in volume of the hippocampus are both important markers of Alzheimer's disease (AD).
-
Compared with individuals at low familial risk of the development of depression, high-risk individuals have reduced hippocampal volume, indicating that neuroanatomic anomalies associated with depression may precede the onset of a depressive episode and influence the development and course of this disorder.
-
The hippocampal volume increases after ECT, supporting the hypothesis that hippocampus may play a central role in the treatment of depression.
-
The findings indicate for the first time in humans that PTSD is associated with selective volume loss of the CA3/dentate gyrus subfields, consistent with animal studies, implying that chronic stress suppresses neurogenesis and dendritic branching in these structures.
-
Imaging studies have consistently documented hippocampal volume reductions in depression.
-
These results indicate that in both healthy subjects and patients with schizophrenia hippocampal volume is plastic in response to aerobic exercise.
-
Prior work has demonstrated that the memory dysfunction of Alzheimer's disease (AD) is accompanied by marked cortical pathology in medial temporal lobe (MTL) gray matter.
-
We used a previously validated automated machine learning algorithm based on adaptive boosting to segment the hippocampi in baseline and 12-month follow-up 3D T1-weighted brain MRIs of 150 cognitively normal elderly (NC), 245 mild cognitive impairment (MCI) and 97 Dementia of the Alzheimer's type (DAT) ADNI subjects.
-
This study investigated the relationship between cortisol secretion and hippocampal volume in first-episode psychosis and healthy controls.
-
The hippocampus is abnormal in schizophrenia.
-
Insulin resistance (IR) is the main pathological condition underlying vascular disorders, such as diabetes and cardiovascular disease, which are well established risk factors for cognitive decline and Alzheimer disease (AD).
-
Smaller hippocampal volume in adolescents at high risk for depression suggests that it may be a vulnerability marker for the illness.
-
The notion of uncontrollable stress causing reduced hippocampal size remains controversial in the posttraumatic stress disorder literature, because human studies cannot discern the causality of effect.
-
Older adults who report more severe acute or chronic pain have smaller hippocampal volumes and lower levels of hippocampal N-acetylaspartate/creatine, a marker of neuronal integrity.
-
Numerous studies have reported a smaller hippocampal volume in Alzheimer's disease (AD) patients than in aging controls.
-
Deterioration of the hippocampus occurs in elderly individuals with and without dementia, yet individual variation exists in the degree and rate of hippocampal decay.
