    The diagnostic value of dopamine transporter imaging and olfactory testing in patients with parkinsonian syndromes2015In: Journal of Neurology, ISSN 0340-5354, E-ISSN 1432-1459, Vol. 262, no 9, p. 2154-2163Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to compare the efficacy of olfactory testing and presynaptic dopamine imaging in diagnosing Parkinsons disease (PD) and atypical parkinsonian syndromes (APS); to evaluate if the combination of these two diagnostic tools can improve their diagnostic value. A prospective investigation of 24 PD patients, 16 APS patients and 15 patients with non-parkinsonian syndromes was performed during an 18-month period. Single photon emission computed tomography with the presynaptic radioligand I-123-FP-CIT (DaTSCAN (R)) and olfactory testing with the Brief 12-item Smell Identification Test (B-SIT) were performed in all patients. DaTSCAN was analysed semi-quantitatively, by calculating two different striatal uptake ratios, and visually according to a predefined ranking scale. B-SIT score was significantly lower for PD patients, but not significantly different between APS and non-parkinsonism. The visual assessment of DaTSCAN had higher sensitivity, specificity and diagnostic accuracy compared to olfactory testing. Most PD patients (75 %) had visually predominant dopamine depletion in putamen, while most APS patients (56 %) had visually severe dopamine depletion both in putamen and in caudate nucleus. The combination of DaTSCAN and B-SIT led to a higher rate of correctly classified patients. Olfactory testing can distinguish PD from non-parkinsonism, but not PD from APS or APS from non-parkinsonism. DaTSCAN is more efficient than olfactory testing and can be valuable in differentiating PD from APS. However, combining olfactory testing and DaTSCAN imaging has a higher predictive value than these two methods separately.

    Do patients with Menieres disease have attacks of syncope?2017In: Journal of Neurology, ISSN 0340-5354, E-ISSN 1432-1459, Vol. 264, p. S48-S54Article in journal (Refereed)
    Abstract [en]

    The aim of the present study was to evaluate the prevalence and associated factors for syncope among patients with Menieres disease (MD). An attack of syncope was defined as a sudden and transient loss of consciousness, which subsides spontaneously and without a localizing neurological deficit. The study used an across-sectional survey design. Information from a database consisting of 961 individuals was collected from the Finnish Meniere Association. The data contained case histories, general health-related quality of life (HRQoL), and impact measurements of the complaints. In the current study sample, syncope occurred in 12.3% of the patients with MD. It was more prevalent among elderly persons and among those with a longer duration of MD. Syncope was significantly associated with disturbances of otolith function reflected as Tumarkin attacks, gait and balance problems, environmental change of pressure, and physical strain. It was also associated with visual blurring; in fact, patients with otolith dysfunction in MD often experience visual field changes. It was also associated with headache, but not with migraine. Syncope was experienced as frightening and HRQoL was significantly worsened. The patient had higher anxiety scores, and suffered more from fatigue. The results demonstrate that neurally mediated syncope occurs in patients with an advanced form of MD who suffer from Tumarkin attacks due to failure in otolith function. The mechanism seems to be triggered through the vestibular sympathetic reflex when the otolith system fails due to disrupted utricular otolithic membrane mediate erroneous positional information from the otolith organ to the vasomotor centres in the brain stem and medulla.

    A 2-year observational study of patients with relapsing-remitting multiple sclerosis converting to glatiramer acetate from other disease-modifying therapies: the COPTIMIZE trial2014In: Journal of Neurology, ISSN 0340-5354, E-ISSN 1432-1459, Vol. 261, no 11, p. 2101-2111Article in journal (Refereed)
    Abstract [en]

    Studies suggest that patients with relapsing-remitting multiple sclerosis (RRMS) who do not benefit from other disease-modifying treatments (DMTs) may benefit from converting to glatiramer acetate (GA). COPTIMIZE was a 24-month observational study designed to assess the disease course of patients converting to GA 20 mg daily from another DMT. Eligible patients had converted to GA and had received prior DMT for 3-6 months, depending on the reasons for conversion. Patients were assessed at baseline and at 6, 12, 18, and 24 months. In total, 672 patients from 148 centers worldwide were included in the analysis. Change of therapy to GA was prompted primarily by lack of efficacy (53.6 %) or intolerable adverse events (AEs; 44.8 %). Over a 24-month period, 72.7 % of patients were relapse free. Mean annual relapse rate decreased from 0.86 [95 % confidence interval (CI) 0.81-0.91] before the change to 0.32 (95 % CI 0.26-0.40; p less than 0.0001) at last observation, while the progression of disability was halted, as the Kurtzke Expanded Disability Status Scale (EDSS) scores remained stable. Patients improved significantly (p less than 0.05) on measures of fatigue, quality of life, depression, and cognition; mobility scores remained stable. The results indicate that changing RRMS patients to GA is associated with positive treatment outcomes.
