A 79-year old male patient developed a brain abscess as infective transformation of a preceding intracerebral haemorrhage after urinary tract infection. The awareness of brain abscess formation at the site of intracerebral haemorrhage is crucial for early diagnosis and treatment of this rare but potentially fatal complication.
Fractal dimension (FD) is a natural measure of the irregularity of a curve. In this study the performances of three waveform FD estimation algorithms (i.e. Katz's, Higuchi's and the k-nearest neighbour (k-NN) algorithm) were compared in terms of their ability to detect the onset of epileptic seizures in scalp electroencephalogram (EEG). The selection of(More)
BACKGROUND Depression and anxiety are common psychiatric symptoms in patients with epilepsy, exerting a profound negative effect on health-related quality of life. Several issues, however, pertaining to their association with psychosocial, seizure-related and medication factors, remain controversial. Accordingly, the present study was designed to(More)
The Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) was developed as a screening tool for symptoms of major depressive episodes in people with epilepsy. Our study describes the development, validation, and psychometric properties of the Greek version of the NDDI-E. A consecutive sample of 101 patients with epilepsy, eligible to participate(More)
OBJECTIVE Depression is common among patients with epilepsy. The aim of our study was twofold: to estimate the prevalence of a major depressive episode and to identify its determinants among patients with epilepsy treated in the largest Greek hospital in Athens. METHODS All consecutive patients with epilepsy that visited the epilepsy outpatient clinic of(More)
Symptoms of psychological distress are relatively common in spasticity patients as a result either of the primary central nervous system insult or as a reaction to the ensuing impairment. Intrathecal baclofen (ITB) is an established treatment for the spasticity with an unknown effect on the psychiatric symptoms. In this study, we evaluate the role of ITB in(More)
This is a case of a 69-year-old male patient with long-standing iatrogenic hypoparathyroidism after total thyroidectomy. The clinical evaluation revealed mild neurological symptoms and excessive brain calcinosis. Intracranial calcification that affects structures other than the basal ganglia and the cerebellum is a rare manifestation of postoperative(More)
This study investigated whether certain cognitive deficits are associated with frontal lobe epilepsy (FLE) aiming to contribute with localization data to the preoperative assessment of epilepsy surgery candidates. We evaluated 34 patients with refractory FLE, 37 patients with refractory medial temporal lobe epilepsy (MTLE), and 22 healthy individuals in(More)
OBJECTIVE Recent cross-disciplinary literature suggests a dynamical analogy between earthquakes and epileptic seizures. This study extends the focus of inquiry for the applicability of models for earthquake dynamics to examine both scalp-recorded and intracranial electroencephalogram recordings related to epileptic seizures. APPROACH First, we provide an(More)
OBJECTIVE We study the effectiveness and safety of intrathecal baclofen therapy for the treatment of spasticity and gait improvement in patients suffering from hereditary spastic paraplegia. METHODS Sixteen patients diagnosed with hereditary spastic paraplegia (mean age: 43 years) were enrolled in this open prospective study. The main inclusion criteria(More)
