They are often anxious and tend to feel guilty. These people have difficulty acknowledging and expressing anger and struggle to get their own needs and goals met. Unable to soothe or comfort themselves when distressed, they require involvement of another person to help regulate their emotions. Psychodynamic Diagnostic Manual
The Psychodynamic Diagnostic Manual (PDM) approaches dependent personality disorder in a descriptive, rather than prescriptive sense and has received empirical support. The Psychodynamic Diagnostic Manual includes two different types of dependent personality disorder:
Passive-aggressive
Counter-dependent The PDM-2 adopts and applies a prototypic approach, using empirical measures like the SWAP-200. It was influenced by a developmental and empirically grounded perspective, as proposed by Sidney Blatt. This model is of particular interest when focusing on dependent personality disorder, claiming that psychopathology comes from distortions of two main coordinates of psychological development:

The anaclitic/introjective dimension. The relatedness/self-definition dimension.The anaclitic personality organization in individuals exhibits difficulties in interpersonal relatedness, exhibiting the following behaviours:

Preoccupation with relationships
Fear of abandonment and of rejection
Seeking closeness and intimacy
Difficulty managing interpersonal boundaries
Tend to have an anxious-preoccupied attachment style.Introjective personality style is associated with problems in self-definition. Differential diagnosis
There are similarities between individuals with dependent personality disorder and individuals with borderline personality disorder, in that they both have a fear of abandonment. Those with dependent personality disorder do not exhibit impulsive behaviour, unstable affect, and poor self-image experienced by those with borderline personality disorder, differentiating the two disorders. Treatment
People who have DPD are generally treated with psychotherapy.
Central centrifugal cicatricial alopecia (CCCA), is a type of alopecia first noticed in African Americans in the 1950s and reported by LoPresti et al. in  1968 as a result of application of petrolatum followed by a stove-heated iron comb. The original theory was that the hot petrolatum would travel down to the hair root, burn the follicle, and after repetitive injury scarring would result. Later CCCA was realized to affect men and women without a history significant for use of such styling techniques. Consequently, the terms "follicular degeneration syndrome" per Sperling and Sau in 1992 and then CCCA per Olsent et al. in 2003 were evolved. Plausible contributing factors may include other African-American styling techniques such as relaxers, tight braids, heavy extensions, certain oils, gels or pomades. Presentation
CCCA usually begins at the central (sagittal) midline of the scalp. It is symmetric and exhibits scarring as the name suggests. It involves solely the top of the scalp or may progress to Hamilton–Norwood scale Type VI or VII. Early symptoms may include pruritus, dysesthesias and tenderness. On examination the skin is thin with few follicular ostia and later in the disease the scalp may appear shiny. Cause
The mechanism of pathology of CCCA remains unknown; thus, the cause has only been postulated and not proven. CCCA is suspected to have a multi-factored cause. However, one theory involves pressure exerted on the internal root sheath leading to damage, which leads to the recruitment of inflammatory cells and the result of scarring.
