Guide
Ataxia - answer✔Loss of coordination, though the power necessary to make the movements is
still present
Cognition - answer✔The mental processes by which a person acquires knowledge, among these
are reasoning, creative actions and solving problems
Paranoia - answer✔A condition whose main characteristic is the delusion that other people are
(in an unclear way) connected to the affected individual
Phobia - answer✔A marked and out of proportion fear within an environmental or situational
context to the presence or anticipation of a specific object or situation

hopelessness (anhedonia)
Hallucination - answer✔False perceptions arising without an adequate external stimulus (as
opposed to illusions, which are misinterpretations of stimuli arising from an external object)
Norepinephrine - answer✔AKA noradrenaline, is a neurotransmitter in both the peripheral and
central nervous systems, producing many effects in the body, the most notable being those
associated with the 'fight or flight' response to perceived danger
Dopamine - answer✔A neurotransmitter that is produced in the substantia nigra, ventral
tegmental area, and hypothalamus of the brain, and dysfunction of signaling associated with this
neurotransmitter has been implicated in different nervous system diseases
