The aim of this preliminary study was to compare the pupil reaction to light in Alzheimer's disease (AD) patients before and after treatment and in normal controls. Ten AD patients diagnosed according to DSM-IV and NINCDS-ADRDA criteria (five medication-free and five under anticholinesterase treatment) and five age- and gender-matched controls took part in(More)
UNLABELLED The aim of the present study was to search for differences between subtypes of major depression with the use of single photon emission tomography. MATERIALS AND METHODS Fifty (50) patients aged 21-60 years suffering from Major Depression according to DSM-IV took part in the study. The SCAN v 2.0 was used to assist clinical diagnosis. The(More)
The aim of the current study was to compare the pupil reaction to light in depressed patients and normal control subjects. Seven depressed patients with melancholic features according to DSM-IV criteria and 14 age- and gender-matched control subjects took part in the study. All were free of any medication for at least 2 weeks. All were aged between 25 and(More)
There are no articles in the international psychiatric literature reporting subclinical visual system disorders in depressed patients, although a disturbance of circadian rhythms is one of the prominent theories of the etiopathogenesis of depression. Fifty patients aged 21-60 years suffering from major depression according to DSM-IV criteria, and 20(More)
The electroretinogram (ERG) to flashes of white light presented under photopic conditions and the pattern reversal visual evoked potentials (PR-VEPs) from both eyes were recorded from 14 patients with multiple sclerosis (MS) with monocular demyelinating optic neuritis (DON) and from 11 patients soon after presenting with monocular demyelinating optic(More)
Suicide is a major problem for psychiatry. Depression is the most common mental disorder related to suicidal behavior. The present study aimed at investigating the relationship between the symptomatology related to death, dying, and suicide and neurobiological factors in depressed patients. Fifty patients aged 21-60 years suffering from major depression(More)
OBJECTIVE To investigate the possibility of impaired central nervous system (CNS) cholinergic transmission in myasthenia gravis (MG), and the effect of eye movements and particularly of micromovements in the psychophysiology of vision. MATERIALS AND METHODS Fourteen patients with clinical manifestations of external ophthalmoplegia due to different causes(More)
We investigated the somatosensory evoked potentials (SSEPs) in 62 healthy children, ten days to twelve years old. Our control group consisted of ten healthy adults, sixteen to thirty-six years old. The stimulus was applied at the median nerve at the wrist and the cerebral SSEPs were recorded by electrodes placed on the contralateral parietal scalp region,(More)
Background: Short Latency Somatosensory Evoked Potentials (SEPs) may serve to the testing of the somatosensory tract function, which is vulnerable and affected in vascular encephalopathy. The aim of the current study was to search for clinical and neuroimaging correlates of abnormal SEPs in vascular dementia (VD) patients.
The difficulties in diagnosing spinal cord lesions due to the cervical spondylosis is well-known in clinical neurology. In order to investigate the contribution of various neurophysiological examinations in the diagnosis in cervical spondylosis, we examined 70 patients suffering from cervical spondylosis, with peripheral nerve conduction studies, F-wave(More)
