AB went to art and craft class and related well with the staffs and other patient. His mood seems to be improving throughout the weeks but his withdrawal symptoms still evident.

Mental State Examination (a week after admission):

Physical examination:

Formulation:

Demographic Details:

• Single, 33 year-old, unemployed man.

Summary:

• Alcohol abuse for 14 years
• Best friend died of car crash 14 years ago, a friend committed suicide early this year, broke up with girlfriend 3 months ago.
• Got fired recently, social welfare funding stopped.

Differential diagnosis:

Severe depressive episode without psychotic symptoms (ICD F32.2) is the most likely diagnosis. AB has all the somatic features of depression upon admission and he has suicidal ideation, which he thought of jumping in front of the train to end his life.

Acute stress reaction (ICD F43.0) was excluded based on the histories and investigations because the onset needs to be within few minutes after the impact of the stressor. Acute stress reaction will resolve immediately within few hours to 3 days(1).

Post-traumatic stress disorder (ICD F43.1) could be a possible cause since depression, insomnia, suicidal ideation and excessive use of alcohol are commonly associated with this disorder. However AB does not meet the diagnostic guidelines of post-traumatic stress disorder in addition of trauma, there must be repetitive, intrusive recollection, or re-enactment of the event in memories, daytime imagery, or dreams(1).

Adjustment disorder (ICD F43.2) could also be a possible cause having had he just lost his friend, girlfriend and his job but it could not be specified just yet as adjustment disorder does not last more than 6 months(1).

Mental and behavioural disorder due to use of alcohol (ICD F10) could also be the likely cause because AB has been having chronic alcohol abuse since 2004. This satisfied criteria of dependence syndrome in which describe in ICD-10 as “cluster of physiological, behavioural, and cognitive phenomena in which the use of a substance or a class of substances takes on a much higher priority for a given individual than other behaviours that once had greater value. A central descriptive characteristic of the dependence syndrome is the desire (often strong, sometimes overpowering) to take psychoactive drugs (which may or may not have been medically prescribed), alcohol, or tobacco. There may be evidence that return to substance use after a period of abstinence leads to a more rapid reappearance of other features of the syndrome than occurs with nondependent individuals(1).”

Aetiology:

AB’s mother has history of depression. His family has not getting on very well since his father went sick for the past years until now. His best friend died in a car crash few years back and another friend committed suicide early this year. His girlfriend just broke up with him 3 months ago. AB has been losing so many people in his life lately. He just got fired and his social welfare was stopped. His drinking problem just gotten worse and he just could not find the way out of his problem.

AB was on Librium detox for 5 days, the aim is to support him through detox and maintain abstinence of alcohol. He keeps on complaining about his past and how he regrets it. Support and therapeutic listening time (reassurance) was given to improve his mood to optimal mental state and reduce his suicidal ideation. Since AB has poor coping skills outside hospital, his consultant discussed to him about the plan to get him a place for rehab for a residential programme. AB was very keen for that but in order to do that, there are few things that need to be done beforehand. He needs to be detoxed off Librium or any antipsychotic medications. Supporting letter from his consultant is needed to put him forward for 30 days Residential Programme. After that, they will set an assessment date and AB could possibly get HSE funding and keep his social welfare benefits.

Discussion:

Based on the history and examination, I think the diagnosis would be severe depressive episode without psychotic symptoms along with alcohol abuse. AB was coping with recent bereavement, work loss and money crisis. He has all the somatic features listed in ICD-10 F.32 with mark loss of appetite, low mood and reduced energy for more than two weeks accompanied by reduced concentration and attention, idea of guilt and unworthiness, pessimistic view of the future, and suicidal ideation(1).

The diagnosis of alcohol abuse is made based on all the criteria given in ICD-10 F10 F1x.2Dependence Syndrome. AB satisfied all the criteria given which are;

“(a) A strong desire to take the substance.

(b) Difficulties in controlling substance-taking behaviour in terms of its onset, termination, or levels of use.

(c) A physiological withdrawal state (see F1x.3 and F1x.4) when substance use has ceased or been reduced, as evidenced by: the characteristic withdrawal syndrome for the substance; or use of the same (or a closely related) substance with the intention of relieving or avoiding withdrawal symptoms.

(d) Evidence of tolerance, such that increased doses of the psychoactive substance are required in order to achieve effects originally produced by lower doses.

(e) Progressive neglect of alternative pleasures or interests because of psychoactive substance use, increased amount of time necessary to obtain or take the substance or to recover from its effects.

(f) Persisting with substance use despite clear evidence of overtly harmful consequences, such as harm to the liver through excessive drinking, depressive mood states consequent to periods of heavy substance use, or drug-related impairment of cognitive functioning; efforts should be made to determine that the user was actually, or could be expected to be, aware of the nature and extent of the harm(1).”

I would say AB is trying to cope by taking alcohols to escape from his negative emotions and in turned being dependant on it. The risk of alcohol abuse is four times higher among persons with major depressive disorder than among those who do not suffer from this condition. Studies also shown that patient with dual diagnosis tend to have high risk of suicide or tempted suicide which justify his condition(2).

AB has good insight about his condition which is very helpful in his prognosis. All he needs for him to get better is a strong motivation and good social support as well as family support(3). In this case, Hope House residential programme is a suitable place for him to undergo his rehab as their aim is to help people become abstinent from mood-altering substances and behaviours and improve the quality of their lives.The programme at Hope House is also designed so that residents learn to become responsible for their own recovery(4).

In relation to his depression, antidepressant is the mainstay treatment for severe episodes, and it is proven that relapse is reduced if it is continued for six months after the end of the episode(5).

Given that AB has suicidal ideation, it is important to have an on-going risk assessment in his management plan given that suicide is more common with people who suffer deppressive episode, alcohol dependence, and largely associated with lack of employment including both unemployment and retirement(6).
