Cannabis Might Worsen Memory and Stopping It Might Improve It

By R. Ryan S Patel DO, FAPA OSU-CCS Psychiatrist

As of 2016, about 37 million individuals in the United States reported using cannabis / marijuana in the last year (1).

This is projected to increase in the future as many states move to legalize medicinal and or recreational cannabis or marijuana use.

As with many things like excessive junk food, excessive alcohol, tobacco, etc. being legal does NOT ALWAYS mean being  healthy.

For example, a recent study looked at cannabis and false memories (2), while another study looked at memory changes after stopping cannabis (3).

What was the first study? (2)

  • 23 healthy people aged 18 to 29 with and without tetrahydrocannabinol (THC).
  • They were asked to learn material while sober.
  • 2 days later, researchers compared memory recall among those who had used cannabis vs those who had not 2 hours before the test.

What were the study results of the first study (2)

In the first study, subjects who used cannabis 2 hours prior to the test were more likely to have false recognition of words and pictures that had not been presented during the sober study session (2).

What does this mean?

This small study suggests that cannabis use might impact academic performance (2), though further study is needed.

What was the second study (3)?

  • 88 individuals (Average age 21 years) who used cannabis at least weekly were randomized to 30 days of abstinence or to a control group, abstinence confirmed through biochemical testing (3).
  • Participants underwent cognitive testing at baseline and then weekly for 4 weeks.

What were the results of the second study? (3)

This 4 week study showed that improvements in memory started at week 1 and continued improvement through week 4. (3)

What does this mean?

  • This small study implies stopping cannabis may improve memory; and further longer, larger studies are underway (3).
  • Subjects used cannabis atleast weekly, and it is unclear if there is a difference in benefit among heavy vs light users.
  • These studies suggest that Cannabis or Marijuana may impact your ability to remember, and may cause false recall during tests; as well as memory improvement after stopping cannabis use.  A previous post showed that cannabis may increase alcohol intake (4).

Strategies for a Successful End of Semester

By R. Ryan S Patel DO, FAPA OSU-CCS Psychiatrist

In academics as with many other aspects of life, successful performance requires a series of steps over time that may or may not appear to be connected.

With multiple deadlines,  projects, exams,  etc all due around the same time; the end of the semester can be a high stress time for students.

Luckily there are a series of science-backed strategies that students can apply to be their best physically, mentally, cognitively, and emotionally to maximize chances of academic success.

What health related activities should I INCREASE my chances of academic success at the end of the semester?

Graduation, Stress, and Summer

 

By R. Ryan S Patel DO, FAPA OSU-CCS Psychiatrist

As the summer nears, many students are anticipating positive experiences such as a break from classes, or fewer classes, study abroad, vacation, time away from academics, work, internship,  job search, etc.

Some students are approaching graduation from college or graduate/professional school.

While these can overall be positive for most students, some students can experience negative emotions during this time.

What are some sources of stress that students can experience as summer approaches?

Some examples include:

  • Stress of graduation, moving, finding a job or internship.
  • Major life transition from being a student to being in the workforce, and related lifestyle changes
  • Increased isolation
  • Change in relationships, friendships, and environment as you move away from college
  • Changes in sleep, eating, and social schedules

What are some negative emotions that students can experience as summer/graduation approaches?

While very little research exists in this area, as college mental health clinicians, this time of year, we will often see students experiencing:

  • Decreased motivation
  • Increase in depression, anxiety
  • Difficulty sleeping
  • Increased feelings of stress
  • Changes in appetite, irritability
  • In some cases, worsening of a pre-existing mental health condition.

What are some ways to manage this?

  • Recognize the changes that you are experiencing as a result of this transition.
  • Think about how you were impacted, and what helped you during previous transition points in your life such as graduating from high school, or undergrad and transitioning to the next level, other life transitions, etc.
  • Consider making a plan to address the upcoming transition
  • Get organized, maintain lists
  • Maintain healhty habits, now more than ever. (see links below)
  • Some students might benefit from making a plan to maintain a connection with friends and other experiences they found meaningful during college
  • It may be helpful to think of ways to incorporate what you liked in the past, into your future transition (summer, life after graduation, etc).
  • Others may find it helpful to identify positive aspects of the upcoming changes
  • Enlist the help of others.
