Progressive cognitive decline is one of the hallmark symptoms of Alzheimer’s disease (AD) which can be modeled by β-amyloid injection into specific regions of brain. Since epigallocatechin-3-gallate (EGCG) is a potent antioxidant agent which its role against oxidative stress and inflammation has been shown in prior studies, we tried to determine whether EGCG administration protects against β-am...
Introduvtion: Alzheimer's disease is one of the most common neurodegenerative diseases in the brain. The aim of this study was to evaluate the effect of lovastatin and folic acid on cognitive deficit by induced lesion in nucleus basalis magnocellularis Methods: In this experimental study, 56 male Wistar rats were randomly divided into 8 groups: (7 rat in each group): control(intact), Nucleus b...
Perinatal brain lesion is a risk factor for development, making parents of such children particularly worried about consequences it may have on the child's cognitive and language development. Although literature findings on the outcome of perinatal brain lesion are inconsistent, most of the studies have found a positive general outcome, but also subtle deficits that affect the child's academic ...
Following brain lesions, previously normal patients sometimes exhibit criminal behavior. Although rare, these cases can lend unique insight into the neurobiological substrate of criminality. Here we present a systematic mapping of lesions with known temporal association to criminal behavior, identifying 17 lesion cases. The lesion sites were spatially heterogeneous, including the medial prefron...
OBJECTIVE Freezing of gait is a disabling symptom in Parkinson disease and related disorders, but the brain regions involved in symptom generation remain unclear. Here we analyze brain lesions causing acute onset freezing of gait to identify regions causally involved in symptom generation. METHODS Fourteen cases of lesion-induced freezing of gait were identified from the literature, and lesio...
Objective To investigate the relationship between brain volume and disability worsening over ≥3 years in the natural history of primary progressive multiple sclerosis using data from the placebo group of the INFORMS trial (n = 487; clinicaltrials.gov NCT00731692). Methods Magnetic resonance imaging scans were collected annually. Brain volume loss was determined using SIENA. Patients were stra...
Introduction: The silent brain lesions detected by MRI were fairly common not only in first-ever stroke but also in normal elderly subjects. Some recent studies show the possible role of silent sub-cortical brain infarction in ischemic stroke. The aim of this study was to evaluate the frequency of silent sub-cortical brain infarction in acute first-ever ischemic stroke. Methods: In this descrip...
