Your Brain on Drugs RED RIBBON WEEK 2015
2
Effect of Drugs on the Developing Brain Your brain does not finish developing until a person is around 20 years old. The brain of people under 21 years of age is very different from people over 21 years of age.
3
Effect of Drugs on the Developing Brain Your brain is like a computer! It comes into the world with the basic operating systems, central nervous systems, respiratory system, reflexes, etc.
4
Effect of Drugs on the Developing Brain It does not have all the software – the programs for vision, speech, emotions, memory, abstract thinking, problem solving, and attention and concentration. The brain needs input from the 5 senses to build these capacities.
5
Effect of Drugs on the Developing Brain The brain not only grows bigger – from one pound at birth to three pounds at adulthood – but it continues to “program” itself for 20 years, completing the developmental process that started before birth.
6
Effect of Drugs on the Developing Brain As you grow, your brain is creating a complete human being, who is ready to function independently. The brain is on a schedule, with each stage of development allotted a specific period of time for completion.
7
Effect of Drugs on the Developing Brain In other words, if anything prevents the brain from accomplishing a developmental task on its schedule, it has to skip that task. Any substance that interferes with how the brain operates during this 20- year period of development such as psychoactive drugs, can change the course of a person’s physical, mental, emotional, and social development. Psychoactive means mind or mood altering.
9
Effect of Drugs on the Developing Brain Some psychoactive drugs are prescribed to treat malfunctions in the brain such as seizures and degenerative diseases such as Alzheimer’s and Parkinson’s. When prescribed, these drugs can be life saving. “Self-prescription” of psychoactive drugs can be harmful or deadly.
10
Effect of Drugs on the Developing Brain Type of harmful psychoactive drugs include: alcohol cocaine amphetamine methamphetamine marijuana hallucinogens inhalants nicotine caffeine opiates sedatives steroids
11
Effect of Drugs on the Developing Brain Psychoactive drugs change how the brain cells communicate with each other by interfering with neurotransmitters – the messengers that go between brain cells translating the messages to ensure accurate and timely communication between cells. Psychoactive drugs act like computer viruses; they change, delete, or scramble the code that our computer – the brain – uses to operate.
12
Effect of Drugs on the Developing Brain They deactivate and activate the brain centers that control speech, hearing, vision, fine movements, gross movements, learning, anger, fear, pain, pleasure, hunger, etc. For any brain, non-prescribed psychoactive drugs can change the way people think, feel, and behave. They are altered!
13
Effect of Drugs on the Developing Brain For a brain that is on a developmental schedule, turning off brain centers, even for a short while, can be devastating. The use of drugs by children and teens can permanently alter their mental and social development, which is not evident until well after their use. Missed developmental tasks in teenagers can be devastating and hidden until they need what did not get developed
15
Post-Test When does the brain complete its development? How much does the average brain weigh at birth? When fully grown? What does psychoactive mean? Are there positive uses for psychoactive drugs? What?
16
Post-Test What do psychoactive drugs do in the brain – how do they operate? Why is the use of non-prescribed psychoactive drugs more dangerous for children and adolescents than for adults? What, if any, piece of information about psychoactive drugs surprised you?
