Intracranial Arterial Stenosis and Resin of Cannabis Use

There is an association between intracranial arterial stenosis and ischemic stroke in young adults. The aim of this study is to evaluate the prevalence of intracranial arterial stenosis in asymptomatic regular resin of cannabis users in comparison with control subjects.

Inclusion criteria

  • regular resin of cannabis users

Exclusion criteria

Treatment and study plan

Cerebral MRI and MRA

Other

Primary outcomes

  1. Presence of intracranial arterial stenosis on cerebral MRA

    Time frame: 3 months

    Rate on cerebral MRA the presence of cerebral Intracranial Arterial Stenosis segmental narrowing defined by at least two intra-cranial arteries compared with a cohort of non cannabis controls subjects.

Secondary outcomes

  1. -Silent ischemic stroke on cerebral MRI

    Time frame: 3 months

    Evaluate on cerebral MRI the presence of sequelae of ischemic stroke defined by a parenchymal hyperintensity in a vascular territory defined on a T2 sequence.

  2. -new intracranial arterial stenosis at 3 month follow-up

    Time frame: 3 months

    Evaluate a cerebral MRA at 3 months the presence of new intracranial stenosis among cannabis users, according to the prosecution or stopping use

  3. -Reversibility of intracranial arterial stenosis at 3 month follow-up

    Time frame: 3 months

    Evaluate on cerebral MRA at 3 months reversibility stenosis present at T0 in cannabis users having stopped their consumption
