Amphetamines Flashcards
Amphetamines
-reverses the direction
-causes the sporadic release of DA + NE
-inhibits the enzymes that break down NE + DA
-all three increase DA + NE
Why do we use Amphetamines for ADHD?
-all symptoms of ADHD can be linked to an area of the brain
-Prefrontal cortex is asleep and needs to wake up to pay attention
Drugs used to treat ADHD?
Aderall + Ritalin (not as commonly used bc of heart problems)
Areas of the brain linked to ADHD
- Dorsal Acc - Selective Attention
- Pre Frontal Cortex - hyperactive symptoms
-Dorsal Lateral PFC - sustained attention + problem solving
-Orbitofrontal cortex - impulsive symptoms
What do ADHD meds do?
–Low levels of NE in people with ADHD. Ritalin + Adderall increase NE
- Locus Correus talks to Prefrontal Cortex -> makes a lot of NE (Adderall blocks NE transporter)
-glutamate from a2 NE receptor depolarizes cell
Ritalin & Cocaine
both block DAT, causing dopamine to build up in the synapse
What happens if you take Adderall and you weren’t prescribed?
-adderall is fixing an imbalance so it affects people differently for someone who doesn’t have ADHD
-theres an optimal level of NE + DA that its optimal for focus. An excessive amount of NE+DA makes you stressed and too little makes you fatigued
Amphetamines & Seizures
- seizures are caused by excitotoxicity which is too much glutamate in the synapse
- Theres an increase glutamate release from Adderall and too much can cause a seizure
