[Diagnostic criteria and differential diagnosis of Parkinson’s disease]

TAKÁTS Annamária

[The clinical diagnosis of Parkinson’s disease is based on the identification of some combination of the clinical motor signs of bradykinesia, rigidity, tremor and postural instability. Three levels of diagnostic confidence are differentiated: possible, probable, and definite. The diagnosis of possible and probable Parkinson’s disease based on clinical criteria alone, while definite diagnosis requires neuropathologic confirmation. To differentiate Parkinson’s disease (idiopathic Parkinsonian syndrome) and other Parkinsonian syndromes is of increasing importance considering the therapy and life expectancy of the patients. Recently the functional imaging technics have been more and more helpful in the early differential diagnosis of Parkinson’s disease.]

[Asymptomatic ischemic cerebrovascular disorders and neuroprotection with vinpocetine]

HADJIEV Dimiter

[The asymptomatic ischemic cerebrovascular disorders (AICVD) is an early manifestation of cerebrovascular disease. It is also known as latent insufficiency of the cerebrovascular circulation or as asymptomatic cerebrovascular disorders. Recently, the term subclinical disease, detected noninvasively, has been introduced by American Heart Association. The diagnosis is based on the following criteria: evidence of vascular risk factors; episodic nonspecific complaints without any focal cerebral symptoms; mild cognitive deficit, detected by neuropsychological tests; carotid ultrasonography often shows intimal-medial thickening, atherosclerotic plaques and carotid stenosis; CT and MRI occasionally reveal silent cerebral infarctions, white matter hyperintensities or cerebral atrophy; regional hypoperfusion above the ischemic threshold is also seen by rCBF measurements. Treatment of the AICVD, modifying the vascular risk factors and using neuroprotective agents, should be the cornerstone of primary prevention of ischemic stroke and cognitive decline, caused by cerebrovascular disorders. Vinpocetine has been found to interfere with various stages of the ischemic cascade: ATP depletion, activation of voltagesensitive Na+- and Ca++-channels, glutamate and free radicals release. The inhibition of the voltage-sensitive Na+- channels appears to be especially relevant to the neuroprotective effect of vinpocetine. Pronounced antioxidant activity of the drug could also contribute to the neuroprotection. PET studies in primates and man showed that 11C labelled vinpocetine passes the blood-brain barrier rapidly. Heterogeneous brain distribution of the compound was observed mainly in the thalamus, basal ganglia, occipital, parietal and temporal cortex, regions which are closely related to the cognitive functions. PET studies in chronic ischemic stroke patients revealed favourable effects of vinpocetine on rCBF and glucose metabolism in the thalamus, basal ganglia and primary visual cortex. It seems, vinpocetine, affecting the multiple mechanisms of the AICVD, could be of benefit for the treatment in this early stage of cerebrovascular disease. Vinpocetine may also become a new therapeutic approach to prophylactic neuroprotection in patients at high risk of ischemic stroke.]

[Is there any importance of the Leiden mutation in the pathogenesis of ischaemic stroke?]

PONGRÁCZ Endre, TORDAI Attila, CSORNAI Márta, BÉLA Zsuzsanna, NAGY Zoltán

[Background - There are conflicting data about the role of Leiden mutation in the pathogenesis of cerebral arterial thrombosis. In order to obtain relevant data, authors investigated the prevalency of factor V Leiden (A506G) both in healthy subjects and in a subgroup of ischaemic stroke patients. Matherial and methods - Blood samples of 171 healthy persons and 254 ischaemic stroke patients were examined by PCR method for Leiden mutation. Ischaemic lesions in the stroke group were documented by CT or MRI. A routin questionnaire was used to study the family history of vascular events (hypertension, diabetes, POAD, stroke, myocardial infarction) of patients. Conventional vascular risk factors of patients were also documented. Results - The prevalence of Leiden mutation was 7.2% in healthy persons and 11.9% in stroke patients. The OR for 254 patient was 1,45 (0.71-2.97). In the subgroup of young patients: age <50 (n=134) the OR was 1.67 (0.75-3.70) and in the elderly patients group: age >50 (n=120) the OR was 1.21 (0.50-2.89). In the family history of stroke patients having Leiden mutation (hetero- and homozigosity) the stroke prevalence was higher (p=0.01). In the ischaemic stroke group, age<50 with polymorphism a tight correlation with hyperlipidaemia (p=0.03) was found. In the group of age<50 with heterozigosity for Leiden, a lower plasma fibrinogen concentration (p=0.02) was found. The polymorphism showed no correlation with the hypertension, hyperuricaemia, migraine, diabetes mellitus, smoking, alcohol consumption and CDS status of patients. Conclusion - When comparing stroke patients to control population there is no significant increase in the frequency of Leiden mutation. Leiden mutation together with hyperlipidaemia and stroke in the family history results in high risk for ischaemic stroke in young patients.]

Evaluation of anxiety, depression and marital relationships in patients with migraine

DEMIR Fıgen Ulku, BOZKURT Oya

Aim - The aim of this study was to evaluate the frequency and characteristics of attacks in patients with migraine, to determine the effects of anxiety or depressive symptoms, and to evaluate the marital relationships of patients with migraine. Method - Thirty patients who were admitted to the neurology outpatient clinic of our hospital between July 2018 and October 2018 and were diagnosed with migraine according to the 2013 International Headache Society (IHS) diagnostic criteria were included in this cross-sectional study. Age, sex, headache frequency and severity, depressive traits, marital satisfaction and anxiety status were examined. We used the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Maudsley Marital Questionnaire (MMQ) and Visual Analogue Scale (VAS) for measuring relevant parameters. Results - The mean severity of migraine pain according to VAS scale was 6.93 ± 1.41 and the mean number of migraine attacks was 4.50 ± 4.24. The mean BDI score of the patients was 12.66 ± 8.98, the mean MMQ-M score was 19.80 ± 12.52, the mean MMQ-S score was 13.20 ± 9.53, the mean STAI-state score was 39.93 ± 10.87 and the mean STAI-trait score was 45.73 ± 8.96. No significant correlation was found between age, number of migraine attacks, migraine duration, migraine headache intensity, and BDI, STAI and MMQ scores (p>0.05). But there was a positive correlation between MMQ-S and scores obtained from the BDI and STAI-state scales (p<0.05). Conclusion - In this study more than half of the migraine patients had mild, moderate or severe depression. A positive correlation was found between sexual dissatisfaction and scale scores of depression and anxiety.

[IDIOPATHIC TOLOSA-HUNT SYNDROME: FOUR ADDITIONAL CASES]

D Kirbas, B Topcular, ME Ozcan, N Sakalli Karagoz, G Gul, I Aslan Kalyoncu

[Idiopathic Tolosa-Hunt syndrome (ITHS) is a very rare cause of painful ophthalmoplegia characterized by unilateral orbital pain, ipsilateral oculomotor paralysis and prompt response to steroids. In this paper we report 4 additional cases of ITHS. This rare cause of painful ophthalmoplegia effects the cranial nerves due to a granulomatous lesion of unknown etiology in the cavernous sinus or superior orbital fissure. The International Headache Society redefined the diagnostic criteria for ITHS but it is still mostly a diagnosis of exclusion. Careful evaluation and follow-up is essential for diagnosis. Optimal therapy duration and dosage and prophylactic treatment in recurrent cases needs further research.]
