Depression, Mania, Anxiety, and Tourette Syndrome Explained
This paper surveys four psychiatric conditions — depression, mania, anxiety disorders, and Tourette syndrome — examining the major theoretical frameworks proposed to explain each and the pharmacological treatments developed in response. For each condition, the paper reviews psychoanalytic, behavioral, cognitive, humanistic, biopsychosocial, and biological models, noting where research has lent greater support to certain explanations. It then outlines the classes of medications used clinically, their mechanisms of action, and their side-effect profiles. The paper draws on peer-reviewed sources to contextualize these treatments within broader debates about the validity of competing etiological models.

What makes this paper effective
- The paper applies a consistent organizational framework across all four conditions — presenting theoretical models before pharmacological treatments — which makes comparisons across disorders easy to follow.
- It accurately distinguishes between competing theoretical traditions (psychoanalytic, behavioral, cognitive, biological) without conflating them, demonstrating conceptual precision.
- Brief but appropriately cited empirical claims (e.g., Barlow, 2000; Lauber et al., 2003) ground the survey in the research literature rather than relying solely on textbook summaries.
Key academic technique demonstrated
The paper demonstrates the technique of comparative theoretical synthesis: for each disorder, multiple explanatory models are enumerated and then evaluated against the weight of research evidence. Rather than simply listing theories, the author notes which have garnered stronger empirical support and why, modeling the kind of critical evaluation expected in psychology coursework.
Structure breakdown
The paper is divided into four condition-based sections (Depression, Mania, Anxiety Disorders, Tourette Syndrome), each following the same internal structure: theoretical models listed in numbered format, a brief evaluative statement about the research consensus, and a survey of medication classes with mechanisms and side effects. A reference list in APA format closes the paper. This parallel structure aids readability and signals strong organizational awareness.
Theories and Treatment of Depression
According to the DSM-IV-TR, a person must exhibit at least five of nine specified symptoms for a minimum of two weeks to receive a diagnosis of depression. Numerous theoretical frameworks have been proposed to explain the causes of this disorder:
1. Psychoanalytic theories — internal conflicts and a low self-image lead to anger turned inward.
2. Behavioral theories — stressors disrupt normal reinforcement patterns.
3. Cognitive theories — cognitive distortions, cognitive errors, and mistaken underlying assumptions drive depressive thinking.
4. Humanistic theories — an excessive concern with the expectations and values of others leads a person away from genuineness and wholeness.
5. Biopsychosocial models — psychological, biological, and social factors all play a role. An important outgrowth is the diathesis–stress model, which asserts that depression occurs when a preexisting vulnerability (diathesis) is triggered by stressful life events. That vulnerability may be biological, psychological, or both.
6. Biological models — an imbalance of neurotransmitters — specifically serotonin, norepinephrine, and dopamine — is implicated in depression.
Research has generally favored cognitive and biological theories, although this does not substantiate them as the only valid explanations (Lauber, Falcato, Nordt, & Rossler, 2003). The growth of biological models has in turn driven the development of numerous pharmaceutical treatments.
