The parasite Toxoplasma gondii influences the behaviour of infected animals and probably also personality of infected humans. Subjects with a Rhesus-positive blood group are protected against certain behavioural effects associated with Toxoplasma infection, including the deterioration of reaction times and personality factor shift. Here, we searche...

Rhesus-positive and rhesus-negative persons differ in the presence-absence of highly immunogenic RhD protein on the erythrocyte membrane. This protein is a component of NH(3) or CO(2) pump whose physiological role is unknown. Several recent studies have shown that RhD positivity protects against effects of latent toxoplasmosis on motor performance...

Cortisol, along with other hormones of hypothalamo-pituitary-adrenal axis, belongs to one of the main factors influencing psychological and pathognomic factors, intelligence, and memory. The aim of our study was to review a large battery of psychological, performance, IQ and memory tests as to their relation with cortisol, testosterone and estrogen...

Latent toxoplasmosis, protozoan parasitosis with prevalence rates from 20 to 60% in most populations, is known to impair reaction times in infected subjects, which results, for example, in a higher risk of traffic accidents in subjects with this life-long infection. Two recent studies have reported that RhD-positive subjects, especially RhD heteroz...

The RhD protein which is the RHD gene product and a major component of the Rh blood group system carries the strongest blood group immunogen, the D-antigen. This antigen is absent in a significant minority of the human population (RhD-negatives) due to RHD deletion or alternation. The origin and persistence of this RhD polymorphism is an old evolut...

A prospective study was conducted to compare the neuropsychological outcome of surgical versus endovascular treatment in patients with cerebral aneurysms. From April 2001 to 2005, 211 patients with ruptured cerebral aneurysms were treated at the senior author's institution. Of these 211 patients, 75 that were able and willing to undergo neuropsycho...

The capacity of short-term verbal memory and other memory parameters were measured following the therapy for an intracranial aneurysm after 1 month and 1 year. Patients (n = 117) were examined using Auditory Verbal Learning Test (AVLT) which repeatedly measured the capacity of short-term verbal memory. Two measurements carried out after subarachnoi...

Temperament and Character Inventory (TCI) is a relatively new theoretically based method used in personality and personality disorders diagnostics. The influence of social desirability during military selection in comparison with clinical practice has not been studied much. Three different samples vere compared - a military personnel (N=718) before...

Recently, a negative association between Toxoplasma-infection and novelty seeking was reported. The authors suggested that changes of personality trait were caused by manipulation activity of the parasite, aimed at increasing the probability of transmission of the parasite from an intermediate to a definitive host. They also suggested that low nove...

This pilot qualitative study examined the changes in both temperament and character by TCI during psychiatric hospitalization in a sample of 12 patients (4 men, 8 women, age 18-68) treated for depression by farmacotherapy and psychotherapy. Increase in Self-Directedness during hospitalization and stable Harm Avoidance dimensions were found in most...

The International Personality Disorder Examination (IPDE) is a semistructured clinical interview compatible with the ICD-10 and DSM-IV. The first Czech report about the IPDE describes experienee from two samples - mixed psychiatric patients mainly with mood disorders (N = 100, average age 36 yrs, SD = 12.3; 18 - 67 yrs; 42 men and 58 women) and con...

Toxoplasma gondii, a parasitic protozoan, infects about 30-60% of people worldwide. The latent toxoplasmosis, i.e. life-long presence of cysts in the brain and muscular tissues, has no effect on human health. However, infected subjects score worse in psychomotor performance tests and have different personality profiles than Toxoplasma-negative subj...

Cognitive Estimations Test (CET) is becoming a part of many examinations and research studies of excutive functions. It is a short, simple and user-friendly test. Authors present two alternative forms of the CET as a supplement to the original Czech version of the test (TKO, Preiss and Laing, 2001). They describe the CET as a suitable instrument fo...

Authors summarize psychological sequelae of subarachnoid haemorrhage (SAH). They focus on three areas- neuropsychological deficits, outcome to normal life and impact of SAH alone. They emphasise importance of long-term follow up and detailed assessment of cognitive deficits and quality of life.

The authors criticise the contemporary use of norms for interpretation of Raven's Standard Progressive Matrices (Raven, 1938) and emphasise the ageing of norms during last decades. They present the findings in the sample of population (n=1769) examined in Prague Military Hospital in 1999-2001. On the basis of this data the percentile cues for men a...

The authors present clinical approach for personality disorders diagnostics on the basis of low Self-directedness in C. R. Cloninger's TCI (Temperament and Character Inventory) and configuration of temperament profiles of novelty seeking, harm avoidance and reward dependence. They assess temperament dimensions in general male population (N = 543, a...

Paper describes discrimation power of Cloninger's TCI (Temperament and Character Inventory) in psychiatric patients against general population. The authors compare psychiatric patients (N = 54) with three samples derived from general population. Differences between psychiatric patients and general population were found mainly in temperament dimensi...
