Assessment statements

DCS Topic Code Statement Guidance
A.5.A1 Effects on the nervous system of two stimulants and two sedatives.  
A.5.A2 The effect of anesthetics on awareness.  
A.5.A3 Endorphins can act as painkillers.  
A.5.S1 Evaluation of data showing the impact of MDMA (ecstasy) on serotonin and dopamine metabolism in the brain.  
A.5.U1 Some neurotransmitters excite nerve impulses in postsynaptic neurons and others inhibit them.  
A.5.U2 Nerve impulses are initiated or inhibited in post-synaptic neurons as a result of summation of all excitatory and inhibitory neurotransmitters received from presynaptic neurones.  
A.5.U3 Many different slow-acting neurotransmitters modulate fast synaptic transmission in the brain.  
A.5.U4 Memory and learning involve changes in neurones caused by slow-acting neurotransmitters.  
A.5.U5 Psychoactive drugs affect the brain by either increasing or decreasing postsynaptic transmission.  
A.5.U6 Anesthetics act by interfering with neural transmission between areas of sensory perception and the CNS. Examples of sedatives are benzodiazepines, alcohol or tetrahydrocannabinol (THC).
A.5.U7 Stimulant drugs mimic the stimulation provided by the sympathetic nervous system. Examples of stimulants are nicotine, cocaine or amphetamines.
A.5.U8 Addiction can be affected by genetic predisposition, social environment and dopamine secretion.
