Seizure occurrence in the Dominantly Inherited Alzheimer Network observational study was correlated with mutation carrier status in cognitively asymptomatic subjects. This finding suggests that ADAD mutations increase the risk of seizures. Interictal epileptiform discharges measured by electroencephalography EEG and overt seizures have been reported in transgenic mouse models of AD Born, ; Palop and Mucke, Persons with AD are at an increased Fashion Design for seizures Horvath et al.

Recently, the DIAN observational study has reported seizures in 2.

1. Introduction

Based on evidence that AD starts much earlier than its cognitive manifestation Bateman et al. The protocol for the study received approval by the institutional review boards at all participating sites. The study was performed in accordance with the declaration of Helsinki. Written informed consent was obtained from each subject. We analyzed the occurrence of seizures by evaluating this item along with the adverse event forms for all visits included in data freeze 9 in all cognitively asymptomatic participants defined by a CDR score of 0.

B Single Item question for the assessment of seizures.

Time to EAO is the difference in years whole numbers between EAO and the current age of the participant at the time of the visit. The data set was also screened for additional factors that might cause or mimic seizures such as alcohol and substance abuse, syncope, diabetes, and other medical comorbidities, as well as for a history of stroke and other neurologic and psychiatric comorbidities such as traumatic brain injury TBI. Sensitivity, specificity, and the positive predictive value of seizure occurrence with respect to mutation carrier status were calculated using a 2-dimensional contingency table.

We used the first study visit at which presence of seizures was mentioned i. For group comparisons, we put the latest possible time point of seizure occurrence in relation to EAO. To compare seizure frequency of asymptomatic carriers of ADAD mutations i.

Mutation carriers were significantly younger than noncarriers and had a longer time to the EAO of their family mutations. Otherwise, no significant baseline differences between the 2 groups were found Table 1. No statistically significant difference in distribution of APOE genotypes between mutation carriers and noncarriers were found.

Relation of mutation status and seizures. A Proportion of mutation carriers in subjects with and without seizures. B Number of subjects with seizures among mutation carriers and noncarriers. Occurrence of seizures corresponds to a sensitivity of 6.

It is possible that a larger sample size would verify this association because a theoretical calculation in an assumed sample with unaltered gene mutation distributions but threefold size would result in a more suggestive p value of 0. On average, the latest possible time point of seizure occurrence determined with the method described previously was 14 years before EAO standard deviation Fluid-attenuated inversion recovery magnetic resonance images in these 3 cases did not reveal any apparent epileptogenic brain lesions related to TBI, such as temporobasal or other cortical contusions.

No other possibly contributing factors were evident in individuals affected by seizures Table 2.]
