Frontotemporal dementia should be considered in adults aged 50–75 years presenting with behavioural or language changes. After Alzheimer disease, it is the second most common cause of dementia among adults younger than 65 years.1 Frontal and temporal lobe degeneration results in behavioural or language impairment.
Normal pressure hydrocephalus is a form of adult hydrocephalus with ventriculomegaly in the absence of any structural blockage of the cerebrospinal fluid circulation.
Normal pressure hydrocephalus is a partially reversible cause of dementia, manifesting with a triad of cognitive impairment, gait disturbance and urinary incontinence.
A detailed cognitive assessment, neurologic examination and brain imaging is necessary to exclude alternative causes and confirm the diagnosis.
High-volume lumbar puncture with pre- and postprocedure gait assessment is recommended as a confirmatory test before a decision is made regarding therapeutic interventions such as shunting.
Purpose of review: Prescribed and non-prescribed cannabis use is common. Providers in specialties treating chronic pain – primary care, pain management, and neurology–will be coming across medical cannabis as a treatment for chronic pain, regardless of whether they are prescribers. It is important to be aware of the systemic and syndromic complications of acute and chronic cannabis use in the differential diagnosis of cardiac, cardiovascular, cerebrovascular, gastrointestinal, and psychiatric disorders.
Recent Findings: Medical cannabis is legal in 36 states. Studies have shown several potentially serious adverse effects associated with cannabis use.
Summary: Cannabis use has the potential to cause several complications that can be easily overlooked without a preexisting high index of suspicion.
