NCT04419272

Brief Summary

Methylphenidate (MPH) is a stimulant, FDA-approved for the treatment of attention deficit hyperactivity disorder (ADHD). It is unknown, however, if stimulants would be of benefit for memory and thinking problems due to epilepsy. In this study, participants will be assigned randomly (i.e., by flip of a coin), to a group that takes MPH and a group that takes a placebo (sugar pill). Participants will not know the group to which they have been assigned. Tests of attention and memory will be completed before taking the study pills and at Week 8. All participants will then have the option of taking MPH for the next two months, and attention and memory will be tested again at Week 16. The study will determine whether methylphenidate is helpful for the treatment of attention and memory problems in adults with epilepsy, and whether the medication is safe and beneficial when taken over an extended time period.

Study Arms (3)

Methylphenidate

EXPERIMENTAL

Subjects who will receive methylphenidate in the double-blinded period; when assigned to the active drug, the dosage of MPH will begin at 10mg twice per day, at 8am and 12pm, for one week. The dosage will then increase to 20mg twice daily, at 8am and 12pm, for the next 7 weeks.

Drug: Methylphenidate

Placebo

PLACEBO COMPARATOR

Subjects who will receive placebo in the double-blinded period; when assigned to receive the placebo during the double-blinded period, subjects will be given a sugar pill for 8 weeks. The sugar pill will be taken twice per day, at 8am and 12pm.

Other: Placebo

Open-Label Methylphenidate

OTHER

All subjects will be offered open-label methylphenidate during Weeks 9-16. the dosage of MPH will begin at 10mg twice per day, at 8am and 12pm, for one week. The dosage will then increase to 20mg twice daily, at 8am and 12pm, for the next 7 weeks.

Drug: Methylphenidate

Interventions

10mg twice per day, at 8am and 12pm, for one week, then increased to 20mg twice daily, at 8am and 12pm, for the next 7 weeks during the double-blinded period.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • SUBJECTS WITH EPILEPSY
  • Participants will include adult subjects with focal-onset epilepsy, based on clinical history, imaging studies and ictal and/or interictal EEG interpreted by a clinical epileptologist. Seizures may be symptomatic, idiopathic, traumatic, or non- traumatic in etiology. Subjects must have self-reported cognitive dysfunction. Subjects must also meet the following eligibility criteria:
  • Age 18 years of age or older;
  • Capacity to provide informed consent;
  • Ability to live independently and complete activities of daily living;
  • Stable seizure frequency at the time of enrollment, such that the subject's treating physician does not believe a change in ASM regimen to be warranted during the trial (ASMs should remain unchanged during the 16 weeks of participation unless absolutely required clinically due an unanticipated change in seizure frequency or severity);
  • Fluency in written and spoken English.
  • CONTROLS \*DO NOT UNDERGO ANY DRUG OR PLACEBO INTERVENTION Two additional subject groups will be included, to control for effects of repeated testing in the open-label extension phase: healthy subjects and epilepsy patients without cognitive complaints, who will not receive the study drug at any point during the study. Epilepsy patients without cognitive deficits must otherwise meet all of the above criteria.
  • Age 18 years or older;
  • Capacity to provide informed consent;
  • Ability to live independently and complete activities of daily living;
  • Fluency in written and spoken English.

You may not qualify if:

  • SUBJECTS WITH EPILEPSY
  • Subjects with epilepsy with or without cognitive complaints will be excluded from participation for:
  • Psychogenic, non-epileptic spells
  • Delirium in the past year
  • A history of alcohol or illicit drug abuse;
  • Generalized tonic-clonic or other generalized motor seizure(s) within 48 hours or focal-onset seizures with impaired awareness within 24 hours of neuropsychological testing;
  • Status epilepticus in the past year;
  • Neurosurgery within the past 6 months;
  • Active suicidal plan/intent in the past 6 months, a history of suicide attempt in the last 2 years, more than 1 lifetime suicide attempt, and/or current high-risk suicide flag in the medical record;
  • Psychotic disorders
  • Severe anxiety (\>26 on the Beck Anxiety Inventory \[BAI\]) and impulse control disorders;
  • Untreated sleep disorders;
  • Use of narcotic or other sedating medications within 6 hours of testing (i.e., diphenhydramine);
  • Concurrent severe major medical illness (i.e., cancer requiring chemotherapy or resection)
  • Prior transient ischemic attack (TIA) or stroke
  • +25 more criteria
