Enuresis is one of the most common problems in childhood. Authors indicate three major factors in its etiology: nocturnal polyuria, hiperactive bladder and difficulty to awake when the bladder is full. Alarm treatment is one of the most effective treatments, being successful in 65% of the cases. However, little is known about how it works. This research evaluates the level of urine osmolarity before and after alarm treatment of 25 patients. Patients had their nocturnal urine osmolarity assessed and received alarm treatments for six months, at most. Urine osmolarity was assessed after treatment, regardless of treatment outcome. There were no significant differences in osmolarity levels before and after treatment. However, this result may be due to the small sample. Research is being extended and sample size increased to verify these results. http://dx.doi.org/10.1016/j.neurenf.2012.04.558 Tu-P-2182 Enuresis: Bladder diary before and after an alarm treatment protocol P.

Enuresis is one of the most prevalent problems in childhood. Classification of the disorder between monosymptomatic and non-monosymptomatic is, in most cases, done through invasive procedures such as the urodynamic exam. The bladder diary is the only non-invasive procedure that helps identify precisely symptoms such as urgency, detrusor hyperactivity, polyuria and irregular fluid intake patterns, all of which may indicate non-monosymptomatic enuresis. The bladder diary involves measurement of fluid intake and urine output during the period of two days and can be easily done with the aid of parent at home. In this research, we aimed to find out if the effects of the alarm treatment depend on the enuresis classification. Alarm treatment is one of the most effective treatments available, reaching a 65% rate of success. This research evaluates 25 patients before and after undergoing an alarm treatment protocol. http://dx.doi.org/10.1016/j.neurenf.2012.04.559 Tu-P-2183 Psychiatric phenotype of juvenile myotonic dystrophy 1 includes internalising disorder, borderline intelligence, visual spatial construction disability and attention deficit disorder M.

Aims.– To investigate the psychiatric and cognitive phenotype in young indivi- duals with juvenile form of myotonic dystrophy type 1 (DM1). Methods.– Twenty-eight individuals with DM1 (mean age: 17 years) were asses- sed using standardised instruments and cognitive testing of general intelligence, visual attention and visual spatial construction abilities. Results.– Twenty (70%) patients were held back from advancing grade levels. The mean Full Scale IQ was 73.6 (Â}17.5) and the mean Verbal IQ was significantly superior to the mean Performance IQ. Fifteen (54%) patients had one or more DSM-IV Axis 1 diagnoses, including internalising disorders (pho- bia:n = 7, 25%; mood disorder:n = 6, 21%; other anxiety disorders:n = 5, 18%) and Attention Deficit Hyperactivity Disorder-Inattention Subtype (n = 8, 28.5%). Twelve out of 22 (55%) patients had alexithymia. Cognitive testing found severe impairments in visual attention and visual spatial construction abilities in four of 18 (22%) and 14 of 26 (54%) patients, respectively. No diagnosis was correlated with the transmitting parent’s sex or with CTG repeat numbers. Patients with severe visual spatial construction disabilities had a significantly longer CTG expansion size. Interpretation.– Children and adolescents with juvenile DM1 have frequent DSM-IV Axis 1 diagnoses, with internalising disorders being the most common type of disorder. They also have borderline intelligence and frequent impairments in attention and visual spatial construction abilities. http://dx.doi.org/10.1016/j.neurenf.2012.04.560 Tu-P-2184 Conversion disorder associated with an arachnoids cyst: A case report R.

Arachnoids cysts are rare, benign space-occupying lesions (SOL) formed by an arachnoids membrane including cerebrospinal fluid (CSF) that in most cases they are identified by accident. Conversion disorder is characterized as a defi- cit or distortion in neurological functioning, or symptoms suggesting a general medical condition that is not referable to an organic lesion. We have reported a case of 24-years-old woman that came to psychiatrist with suicide attempt. She had a history of failed marriage and no history of substance abuse. She had a history of dizziness, light-headedness, blurred vision, seizure and hea- dache for a while. Seizure had been identified to be pseudo seizure in more assessments. Diagnosis of Conversion disorder accompanying with adjustment disorder was revealed. In Brain CT-scan, there was an extra axial cystic lesion with the height, frontooccipital and lateral size of approximately 6.4 cm by 4 cm by 2.5 cm respectively in the left anterior middle fossa and Sylvian fissure that was most likely to be an arachnoids cyst. Based on patient’s history, we can say that arachnoids cyst and its symptoms may had a synergism effect on patient’s symptoms of conversion disorder. This case is an example of importance of ruling out medical problems in patients with psychiatric symptoms. http://dx.doi.org/10.1016/j.neurenf.2012.04.561 Tu-P-2185 Psycho-affective development of children affected by congenital toxoplasmosis: About 26 cases J.

Background.– When considering the consequences of congenital toxoplasmosis on the psychological development of a child, there is a prevailing assumption that these are generally of a negative nature. Material and methods.– The objective of the study is the evaluation of the psy- chological development and the cognitive patterns in children infected with congenital toxoplasmosis. This is a 15-year prospective longitudinal study (1996–2010). The studied population consists in 26 children infected with conge- nital toxoplasmosis, followed by multidisciplinary pediatric teams and referred
