OBJECTIVE To assess the value of spectroscopic and perfusion MRI for glioma grading and for distinguishing glioblastomas from metastases and from CNS lymphomas. METHODS The authors examined 79 consecutive patients with first detection of a brain neoplasm on nonenhanced CT scans and no therapy prior to evaluation. Spectroscopic MRI; arterial spin-labeling(More)
OBJECTIVE Although it is well established that cerebral activation increases with higher task load, the potential effects of training have been investigated over brief periods only. Training is of potential clinical relevance since training programs are an essential part of psychiatric therapy. METHOD Cerebral activation during a visual spatial working(More)
There is evidence that adults with borderline personality disorder (BPD) are characterized by abnormalities in frontolimbic brain areas. In this study we aimed to determine whether brain volume alterations already exist in adolescents with BPD. Sixty female right-handed individuals (age range, 14-18 years), 20 with a DSM-IV diagnosis of borderline(More)
PURPOSE To investigate the treatment outcome of patients suffering from skull base chordoma or chondrosarcoma after fractionated stereotactic radiotherapy. METHODS AND MATERIALS We report 45 patients treated for chordoma or chondrosarcoma with postoperative fractionated stereotactic radiotherapy between 1990 and 1997. Patients had CT and MRI for 3D(More)
BACKGROUND Although previous studies demonstrate significant atrophy of the corpus callosum (CC) in patients with Alzheimer's disease (AD), CC alterations in mild cognitive impairment have not been investigated yet. METHODS 21 subjects with mild cognitive impairment, 10 with AD and 21 healthy controls were investigated using magnetic resonance imaging. In(More)
Abnormalities in limbic-thalamic-cortical networks are hypothesized to modulate human mood states. In the present study differences in hippocampal volumes of patients with a first episode of depression, recurrent major depression and healthy control subjects were examined with high-resolution magnetic resonance imaging (MRI). Male patients with a first(More)
OBJECTIVES To determine whether a specific, standardized training regimen can improve muscle strength and physical functioning in people with dementia. DESIGN Double-blinded, randomized, controlled trial with 3-month intervention and 3-month follow-up period in 2006 to 2009. SETTING Outpatient geriatric rehabilitation. PARTICIPANTS Individuals with(More)
BACKGROUND Although minor motor and sensory deficits, or neurological soft signs (NSS), are a well-established finding in schizophrenia, the cerebral changes underlying these signs are only partly understood. We therefore investigated the cerebral correlates of NSS by using magnetic resonance imaging (MRI) in patients with schizophrenia and healthy(More)
BACKGROUND One of the core symptoms of borderline personality disorder (BPD) is the instability in interpersonal relationships. This might be related to existent differences in mindreading between BPD patients and healthy individuals. METHODS We examined the behavioural and neurophysiological (fMRI) responses of BPD patients and healthy controls (HC)(More)
