  1. 1. Depot neuroleptic maintenance treatment: clinical, pharmacological and neuropsychological aspects

    Författare :Eva Tuninger; Lund Psykiatri; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clinical psychology; Psychiatry; laterality.; chronic psychosis; schizophrenia; outcome; maintenance treatment; follow-up; longitudinal; neuropsychology; SPECT; auditory hallucinations; dopamine receptor occupancy; psychosomatics; Psykiatri; klinisk psykologi; psykosomatik;

    Sammanfattning : Neuroleptic maintenance treatment is effective to reduce the risk of further episodes of schizophrenia and other chronic psychoses, except affective. Lack of insight often lead to poor compliance to the prescripted medication. Then, neuroleptics might be given as depot injections. LÄS MER

  3. 2. Brain plasticity and hand function

    Författare :Anders Björkman; Malmö Handkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; Kirurgi; ortopedi; traumatology; Surgery; Medicin människa och djur ; Medicine human and vertebrates ; hand function; nerve injury; brain plasticity; orthopaedics;

    Sammanfattning : The aim of this thesis was to investigate the effects of cortical reorganisational changes following experimental deafferentation and peripheral nerve injury and apply the concept of brain plasticity to enhance sensory re-education following peripheral nerve injury and repair in the hand. In the first two papers the effects on hand function of contralateral deafferentation was investigated. LÄS MER

  4. 3. Vascular receptor changes in ischemic stroke

    Författare :Emelie Stenman; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vascular receptor changes; Ischemic stroke; Endothelin; Angiotensin; Cardiovascular system; Kardiovaskulära systemet; Pharmacological sciences; pharmacognosy; pharmacy; farmakognosi; farmaci; toxikologi; toxicology; Farmakologi;

    Sammanfattning : The present thesis aimed to examine how ischemic stroke affects the vascular endothelin and angiotensin systems in cerebral arteries. To study vascular receptor changes in ischemic stroke transient focal ischemia was induced in rats. LÄS MER

  5. 4. Morphological alterations in frontotemporal dementia

    Författare :Alexander Santillo; Klinisk minnesforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; frontotemporal dementia; diffusion tensor imaging; von Economo neurons;

    Sammanfattning : The present thesis explores alterations in brain morphology in the neurodegenerative disorder of frontotemporal dementia (FTD). With the aim to improve the clinical diagnostics of FTD, we explored the diagnostic potential of measuring morphological alterations in the white matter by diffusion tensor imaging (DTI)- MRI, compared with the more commonly used assessment of grey matter thickness and volume.

  7. 5. MRI at 3 T of brain functions and fibre tracts adjacent to intracranial tumors

    Författare :Danielle van Westen; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; radiology; tomography; Clinical physics; Medicin människa och djur ; Medicine human and vertebrates ; somatosensory cortex; diffusion magnetic resonance imaging; neoplasms; Functional Magnetic Resonance Imaging;

    Sammanfattning : The aims of the studies were: to evaluate the spatial resolution of fMRI at 3 T by studying fingersomatotopy in area 3 b of the primary sensory area (Paper 1); to investigate the potential of fMRI at 3T as a clinical tool for preoperative evaluation of patients with intracranial tumors (Paper 2); to investigate the effect of glioma resection on the spatial extent of fMRI activation as compared to the normal within-subject variability (Paper 3); to determine whether the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) can distinguish tumor-infiltrated edema of gliomas from pure edema of meningiomas and metastases (Paper 4). Results: Strict somatotopic organisation in the primary sensory cortex was shown in the group average; at the subject level the thumb was located laterally, anteriorly and inferiorly to the little finger in 94 % of subjects (Paper 1).
