Parkinson's disease (PD), a chronic progressive neurodegenerative disorder, has a mainly unknown multifactorial etiology. Neuroinflammatory mechanisms might contribute to the cascade of events leading to neuronal degeneration. Toxoplasmosis can be associated with various neuropsychiatric disorders. The most commonly affected central nervous system (CNS)(More)
In this study, we describe and adapt the relevant methods of magnetic resonance (MR) and stereology to estimate total brain volume (TBV), cerebral and cerebellar volume and their volume fractions within the brain. The study included 15 (8 males, 7 females) controls and 15 (8 males, 7 females) patients with Alzheimer's disease. The patients' MR images were(More)
OBJECTIVES Alzheimer's disease (AD) is the most common cause of dementia and, as previous studies have indicated, degenerative changes in the cerebellum occur in AD. It is well known that the cerebellum does not have a symmetric morphology and some pathological disorders, such as schizophrenia, epilepsy, autism and alcoholism, can cause asymmetrical changes(More)
OBJECTIVE To evaluate cerebellar volume changes and the asymmetry of patients with benign paroxysmal positional vertigo (BPPV). METHODS The cerebellar hemispheres` volumetric symmetry were evaluated using a stereological method on MR images. The study included 15 patients with BPPV, and 14 age-, and gender-matched control subjects. The cases were admitted(More)
Brain balance changes have been recognised in migraine, but cerebellar function between or during attacks has been assessed only in a few studies. Previous studies have indicated that migraine affects cerebellar function. In the present study we aimed to evaluate the hemicerebellar volume changes of patients with migraine without aura (MWoA). Volumetric(More)
PURPOSE The human retina contains dopaminergic neurons within the inner retinal layer. Several studies demonstrated dopaminergic neuronal loss in Parkinson's disease (PD) using optical coherence tomography (OCT). Hypothetically, restless legs syndrome (RLS) may have an underlying dopaminergic mechanism and a probable relation to PD is assumed. Therefore, we(More)
Optic nerve damage occurs in Alzheimer disease (AD) related to the loss of the retinal ganglion cells that contribute fibers to the optic nerve and reduction of the density of axons of the optic nerve. In this study the authors evaluated optic nerve volume changes and the relation between the cerebrum and optic nerve volumes in AD patients. The study(More)
