The performance of patients with Parkinson’s disease on the Face-Name Associative Memory Examination

Constantinos Kormas, Ioannis Zalonis, Ioannis Evdokimidis, Constantin Potagas

Neurological Sciences > 2019 > 40 > 2 > 405-407

In this study, we examined the performance of patients with Parkinson’s disease (PD) with different cognitive profiles on the Face-Name Associative Memory Examination (FNAME). We evaluated 71 patients with a comprehensive neuropsychological battery. The results revealed that the group with executive and additional visuospatial deficits demonstrated significantly lower scores on FNAME. This finding...

Hippocampal structural and functional integrity in multiple sclerosis patients with or without memory impairment: a multimodal neuroimaging study

Efstratios Karavasilis, Foteini Christidi, Georgios Velonakis, Dimitrios Tzanetakos, more

Brain Imaging and Behavior > 2019 > 13 > 4 > 1049-1059

The increasing evidence for a pure amnestic-like profile in multiple sclerosis (MS) introduces the role of hippocampal formation in MS episodic memory function. The aim of the present study was to investigate structural and functional hippocampal changes in mildly-disabled MS patients with and without memory impairment. Thirty-one MS patients with or without memory impairment and 16 healthy controls...

Endogenous sex hormones and memory performance in middle-aged Greek women with subjective memory complaints

Eleni Armeni, Michail Apostolakis, Foteini Christidi, Demetrios Rizos, more

Neurological Sciences > 2018 > 39 > 2 > 259-266

The changing hormonal milieu during the menopausal transition may contribute to the development of memory disorders. We aimed to assess the association of sex hormones with memory function in a sample of Greek middle-aged women. This pilot study included 44 women with subjective memory complaints. Memory performance was evaluated using the Hopkins Verbal Learning Test (HVLT), the Brief Visuospatial...

Gray matter and white matter changes in non-demented amyotrophic lateral sclerosis patients with or without cognitive impairment: A combined voxel-based morphometry and tract-based spatial statistics whole-brain analysis

Foteini Christidi, Efstratios Karavasilis, Franz Riederer, Ioannis Zalonis, more

Brain Imaging and Behavior > 2018 > 12 > 2 > 547-563

The phenotypic heterogeneity in amyotrophic lateral sclerosis (ALS) implies that patients show structural changes within but also beyond the motor cortex and corticospinal tract and furthermore outside the frontal lobes, even if frank dementia is not detected. The aim of the present study was to investigate both gray matter (GM) and white matter (WM) changes in non-demented amyotrophic lateral sclerosis...

Memory-related white matter tract integrity in amyotrophic lateral sclerosis: an advanced neuroimaging and neuropsychological study

Foteini Christidi, Efstratios Karavasilis, Ioannis Zalonis, Panagiotis Ferentinos, more

Neurobiology of Aging > 2017 > 49 > C > 69-78

We aimed to investigate structural changes in vivo in memory-related white matter tracts (i.e., perforant pathway zone [PPZ]; uncinate fasciculus [UF]; fornix) using diffusion tensor tractography and evaluate possible associations with memory performance in nondemented patients with amyotrophic lateral sclerosis (ALS). Forty-two ALS patients and 25 healthy controls (HCs) underwent a 30-directional...

Preoperative neuropsychological presentation of patients with refractory frontal lobe epilepsy

Panayiotis Patrikelis, Stylianos Gatzonis, Anna Siatouni, Elias Angelopoulos, more

Acta Neurochirurgica > 2016 > 158 > 6 > 1139-1150

Background 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. Methods We evaluated 34 patients with refractory FLE, 37 patients with refractory medial temporal lobe epilepsy (MTLE), and 22 healthy individuals in attention, psychomotor...

Determinants of stigma in a cohort of hellenic patients suffering from multiple sclerosis: a cross-sectional study

Maria Anagnostouli, Serafeim Katsavos, Artemios Artemiadis, Markos Zacharis, more

BMC Neurology > 2016 > 16 > 1 > 1-10

Background Patients suffering from several neurologic disorders may bear the “stigma” of their disease, being disqualified from full social acceptance. Although stigma is considered to be present in Multiple Sclerosis (MS), the factors that influence its levels are ambiguous. Aim of our study was to examine, for the first time in the literature, the basic determinants of stigma in a Hellenic MS-patients...

Integration of computers in cognitive assessment and level of comprehensiveness of frequently used computerized batteries

Eleftheria Dede, Ioannis Zalonis, Stylianos Gatzonis, Damianos Sakas

Neurology, Psychiatry and Brain Research > 2015 > 21 > 3 > 128-135

Computerized cognitive assessment has become a new trend in neuropsychology as, over the recent years, clinicians have recognized its advantages and several computerized tools have been produced worldwide. Automated test administration and scoring are time-saving and allow examiners to focus on the examinee’s behavior during testing. Also, automation standardizes administration procedure, permits...

Clinical and cognitive implications of cerebrospinal fluid oligoclonal bands in multiple sclerosis patients

Maria Anagnostouli, Foteini Christidi, Ioannis Zalonis, Chryssoula Nikolaou, more

Neurological Sciences > 2015 > 36 > 11 > 2053-2060

The presence of cerebrospinal fluid oligoclonal bands (CSF-OCB) in Caucasian patients with multiple sclerosis (MS) is supportive of diagnosis, though the relation with patients’ clinical and specifically cognitive features has never been established or thoroughly examined. Thus, we investigated the clinical and for the first time the cognitive profile of MS patients in relation to CSF-OCB. We studied...

Uncinate fasciculus microstructure and verbal episodic memory in amyotrophic lateral sclerosis: a diffusion tensor imaging and neuropsychological study

Foteini Christidi, Ioannis Zalonis, Stavroula Kyriazi, Michalis Rentzos, more

Brain Imaging and Behavior > 2014 > 8 > 4 > 497-505

The present study evaluates the integrity of uncinate fasciculus (UF) and the association between UF microstructure and verbal episodic memory (as one of the cognitive functions linked to UF) in non-demented patients with amyotrophic lateral sclerosis (ALS) using diffusion tensor imaging (DTI). We studied 21 patients with ALS and 11 healthy, demographically-comparable volunteers. Fractional anisotropy,...

Could a structural damage mimic a Parkinson plus syndrome?

Athanasia Alexoudi, Ioannis Zalonis, Pantelis Stathis

Open Medicine > 2013 > 8 > 4 > 450-454

Corticobasal syndrome (CBS) is a progressive disease that includes a heterogeneous neuropathological spectrum. In the majority of cases, corticobasal degeneration (CBD) is the underlying disease. Clinical heterogeneity is reflected in the clinical presentation of the syndrome and consequently misdiagnosis is common. Our case is of interest because the symptoms, the poor response to L-dopa and the...

Trail Making Test error analysis in classic motor neuron disease

Foteini Christidi, Evangelia Kararizou, Nikolaos I. Triantafyllou, George P. Paraskevas, more

Neurological Sciences > 2013 > 34 > 8 > 1367-1374

The use of non-traditional scores in neuropsychological assessment allows for pattern analysis of test performance, commonly referred to as Quantified Process Approach (QPA). In the present study, the QPA was taken to study error rates on the Trail Making Test (TMT) in 26 non-demented patients with classic motor neuron disease (cMND), who commonly present with impaired cognitive flexibility, and 26...
