Comorbidity of Personality Disorders and Substance Abuse Disorders


There are an estimated 44%-60% of people who have been diagnosed with substance use disorder who also qualify with symptoms pertaining to a minimum of one personality disorder.  Personality disorders include antisocial personality disorder, avoidant personality disorder, borderline personality disorder, obsessive-compulsive personality disorder and schizoid personality disorder.  Each of these personality disorders have their own symptoms and characteristics, but generally speaking any personality disorder affects people cognitively, which is the way people look at themselves and the world in general, affectation, which is the level of reaction to any one thing, as well as interpersonal functioning and the level of impulse control a person has.  A person can suffer from mood swings, anger outbursts or alcohol or substance abuse.

A person who is diagnosed with a personality can also have a second diagnosis of substance abuse disorder.  This is defined as:

 

 

 

 

 

 

“A complex behavioral disorder characterized by preoccupation with obtaining                     alcohol or other drugs (AOD) and a narrowing of the behavioral repertoire towards          excessive consumption and loss of control over consumption.  It is usually also           accompanied by the development of tolerance and withdrawal and impairment in social and occupational functioning.” (www.cdad.com)

A patient must present with certain symptoms in order to be diagnosed with substance abuse disorder, the symptoms are the behaviors someone would expect from anyone with a substance abuse disorder, but they are not usually so obvious to the patient.  The symptoms include a tolerance of the substance or a need for more and more of the substance because it is harder and harder to feel the effects of the substance, withdrawal when the substance is not used on a regular basis, the substance being used for longer than the patient thought they would be using it for, the patient having a continuous desire to control the habit of using the substance but is unsuccessful at doing so, the patient spending a lot of time trying to find or use the substance or coming off of the substance, the patient giving up activities in multiple areas of their life in order to have the opportunity to use the substance, and continuing use even though it is causing health problems to the patient.

The diagnosis of substance abuse disorder comes about when the patient has become increasingly more tolerant and dependent on their chosen substance.  After the body becomes accustomed to having that substance available on a regular basis, the body will react with withdrawal symptoms which can include headaches, insomnia, and hallucinations and could include aggression, paranoia or promiscuous behavior.  Most patients live in denial when it comes to admitting they have a problem and have to get past that denial in order for any type of treatment to help them.

When a patient is diagnosed with both of these disorders at the same time it is considered co-morbidity of substance abuse disorder and personality disorder.  A little over half of patients who have been seen for substance use disorder have also been diagnosed with a minimum of one personality disorder.

There are two treatments that have been established for this type of co-morbidity.  One is called dual focus schema therapy and it combines different life skills such as functional analysis and coping skills training.  This treatment involves 24 sessions and plans for two stages.  The first of these stages is called early relapse prevention and helps the patient develop life skills that will aid the patient in dealing with temptation or actual relapses.  The second stage is called schema change therapy and coping skills work, this stage helps the patient make the changes more concrete and helps the patient develop methods for coping once abstinence is achieved.

Looking at co-morbidity of substance abuse and personality disorders has shown how difficult it can be to diagnose a patient with multiple disorders, especially when it involves substance abuse because substance use is so common and it seems there really is a fine line between the two.

Comparing and Contrasting Dissociative Identity Disorder (DID, Multiple Personality Disorder) with Conversion Disorder (CD)


Dissociative Identity Disorder and Conversion Disorder are similar in that they both stem from stressful events.  In Dissociative Identity Disorder a personality is formed when extreme child abuse or sexual abuse is experienced.  With Conversion Disorder it is a more recent event like a rape or physical or emotional abuse. Other than this similarity the two disorders are quite different.

Dissociative Identity Disorder is a disorder in which the person affected suffers from as little as 2 distinct personalities and can suffer from as many as 100 or more.  Each personality has a very distinct identity, and will often take control of the person and how they act.  Because of the different identities taking over the people lose time.  They don’t remember the period of time that they were not in control and then have a hard time understanding why everything is different, especially in extreme cases when the other identity takes over for years at a time.  Usually an alternate identity takes over when the primary identity experiences something overly stressful.  It is common for people with this disorder to have other disorders or to have problems with substance abuse.  While DID has been known to last a lifetime, treatment can help.  Treatment usually involves psychotherapy and helps the person to integrate the identities into one.  It can be a painful process as well as time consuming, but according to people who have been able to achieve integration, it is definitely worth it.

Alternatively Conversion Disorder affects people in their sensory areas or physically where voluntary movement is concerned.  It is known to be a somatoform disorder and is said to be a large part of why people visit their primary care physicians.  Basically when people shove their emotions and stress too far inward they turn into physical symptoms.  This is called converting.  The conversion of these symptoms can cause a patient to contact their caregiver nine times as often.  The patient does not control the symptoms and can have a surprisingly painful beginning, and diagnosis can become complicated by a true physical illness.

Conversion Disorder has specific risk factors which include the fact that someone is female, men are less likely to receive this diagnosis.  This diagnosis is more common in the teen years, if there is someone in the family who is already receiving treatment for Conversion Disorder, it is likely to continue in the family line.

Differential Diagnosis – Delusional Disorders vs Schizophrenic Disorders


Schizophrenia is characterized by two or more of the following: Bizarre delusions, hallucinations (auditory or visual), disorganized speech, grossly disorganized or catatonic behavior, and/or negative symptoms like blunted affect (affective flattening) or a general lack of desire, drive, or motivation to pursue meaningful goals (avolition).  Subtypes include paranoid, disorganized, catatonic, undifferentiated, or residual types.  Compared with Delusional Disorder (DD), social and occupational dysfunction is clinically significant.  There must be continuous signs of the disturbance that persist for at least 6 months, including at least 1 month of bizarre delusions.  On the whole, schizophrenia is marked by delusions that are “not plausible,” where DD is characterized by delusions that are conceivably possible, even if unlikely.

The essential feature of Delusional Disorder (DD) is the presence of one or more “nonbizarre” delusions that persist for at least 1 month, and which have never escalated to a constellation of symptoms that typify Schizophrenia.  (American Psychiatric Association, Diagnostic and statistical manual of mental disorders, 2000, p. 323)  Subtypes include ertomanic, grandiose, jealous, persecutory, somatic, mixed, and unspecified types.  DD can be distinguished from Schizophrenia by the absence active phase schizophrenia symptoms.  This would include prominent auditory or visual hallucinations, bizarre delusions, disorganized speech, grossly disorganized or catatonic behavior, or negative symptoms.  (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000, p. 327)  In short, DD is comparatively mild in its symptoms when compared with schizophrenia.

In short, the primary differentiating factor between schizophrenia and DD is the word bizarre.  If the delusion is plausible, even if improbable, then the diagnosis is DD.  If the delusion is outlandish, or impossible, then the diagnosis is schizophrenia.  “If delusions are judged to be bizarre, only this single symptom is needed to satisfy Criterion A for Schizophrenia.”  (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000, p. 299)

Paranoid Schizophrenia vs Delusional Disorder


Analysis of the common psychopathological features in the various psychotic disorders suggest that symptoms can be clustered into five main categories: (Os & Kapur, 2009, p. 635)

1)      Psychosis, encompassing positive symptoms of delusions and hallucinations.

2)      Alterations in drive and volition, encompassing negative symptoms including lack of motivation, reduction in spontaneous speech, and social withdrawal.

3)      Alterations in neurocognition, encompassing cognitive symptoms including difficulties in memory, attention, and executive functioning.

4)      Affective dysregulation giving rise to depressive symptoms or 5) manic (bipolar) symptoms.

The term schizophrenia is typically applied to a syndrome that is characterized by a long duration, bizarre delusions, negative symptoms, and few affective symptoms (non-affective psychosis).  (Os & Kapur, 2009)  Formerly called dementia praecox, some of its associated features include inappropriate affect, anhedonia, dysphoric mood, lack of insight, depersonalization, and delrealization.  (Colman, 2009, p. 674)  Schizophrenia affects approximately 0.7% of the world’s population, with prevalence greater in men throughout adulthood, but equal by the end of the risk period.  Schizophrenia is highly heritable, with onset being rare before adolescence or after middle age (although men become ill earlier in life than women).  (MacDonald & Schulz, 2009, p. 495)  Schizophrenia subtypes include paranoid, disorganized, catatonic, undifferentiated, and residual types.  This article will focus on paranoid schizophrenia, which tends to be the least severe subtype of schizophrenia.

“The essential feature of the Paranoid Type of Schizophrenia is the presence of prominent delusions or auditory hallucinations” where no disorganized speech, disorganized or catatonic behaviors, or flat or inappropriate affect is present.  (American Psychiatric Association, Diagnostic and statistical manual of mental disorders, 2000, p. 313)  Differential diagnosis is an exclusionary process since of all the other subtypes must be eliminated before diagnosing the paranoid subtype.  Paranoid schizophrenia sufferers typically have delusions that are persecutory and/or grandiose; they also typically have a recurrent theme.  Hallucinations are usually related to the same content theme as the delusions, and may include the associate features of anxiety, anger, aloofness, and/or argumentativeness.  Onset tends to be later in life when compared with other subtypes of schizophrenia, and the distinguishing characteristics are often more stable over time.  The prognosis is considerably better when compared with other schizophrenia subtypes, especially regarding occupational functioning and independent living.  (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000, p. 314)

“The essential feature of Delusional Disorder is the presence of one or more non-bizarre delusions that persist for at least 1 month.”  (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000, p. 323)  Bizarreness is mostly subjective since it is contingent on socio-cultural norms and expectations.  Bizarre delusions (as in schizophrenia) are “clearly implausible, not understandable, and not derived from ordinary life experiences.”  (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000, p. 324)  In contrast, non-bizarre delusions (as in delusional disorder) involve situations that could conceivably happen in real life… like being followed, poisoned, etc.  Subtypes of delusional disorder are categorized based on the content of the delusions or the theme thereof.  They include erotomanic, grandiose, jealous, persecutory, somatic, mixed, and unspecified types.  This essay will focus on persecutory delusions, although persecutory delusions often coexist with and are comorbid with other delusion types (particularly grandiose, in mixed presentation).

A determination of persecutory delusions is complicated by the fact that the incidence of persecutory thoughts is relatively common among the general population.  (Brown, 2008, p. 165)  “The criteria used to distinguish between these different categories of psychotic disorder are based on duration, dysfunction, associated substance use, bizarreness of delusions, and presence of depression or mania.”  (Os & Kapur, 2009, p. 635)  In delusional disorders, distortions of reality coexist with realms of rational, realistic thinking.  (Blaney & Millon, 2009, p. 361)  Delusional disorders are distinguished from schizophrenia by the absence of active phase symptoms of schizophrenia (e.g. prominent auditory or visual hallucinations, bizarre delusions, disorganized speech, grossly disorganized or catatonic behavior, and/or negative symptoms).  “Compared with schizophrenia, delusional disorder usually produces less impairment in occupational and social functioning.”  (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000, p. 327)

“The assessment of bizarreness is generally absent among lists of delusion dimensions, notwithstanding its key role in the distinction between DD and PS.”  (Blaney & Millon, 2009, p. 365)  To improve decision-making and reduce the chance of misdiagnosis, Brown (2008) suggests we ascertain, to the extent available, base rates of the specific persecutory beliefs (e.g. discrimination and harassment, mental illness stigma, criminal victimization, relationship infidelities, conspiracies, stalking, surveillance, poisoning, etc) in our area.  Secondly, he suggests we consider alternative hypotheses, especially in decisions that have a very low base rate.  While actively searching for disconfirming information, we should postpone decisions until further information is collected.  I agree with his suggestion that we should rely more on information, and less on intuition, when it comes to confirming or disconfirming persecutory beliefs.  (Brown, 2008, p. 172)

Schizophrenia Information Grab-bag


“Schizophrenia is the most crippling of the psychiatric disorders.”  (Blaney & Millon, 2009, p. 298)  That’s a bold first statement.  I was curious as to the reason why typical onset times are younger (sooner) for males as compared to females.  The developmental perception I am accustomed to generally indicate that females “grow up” sooner than males… I am the slightest bit curious what could cause this phenomenon to flip-flop.  Any insight there readers?

Although I was alive during the 1980’s, I was so young that I was wholly unaware of the de-institutionalization that took place during that era.  The statement that prisons have become the de factor health care provider reaffirms my belief that working with that population is absolutely critical to our success as a society.

Typical schizophrenia characteristics include hallucinations, delusions, disorganized speech, grossly disorganized or catatonic behavior, and/or negative affective symptoms.  The text states that the most common types of hallucination consist of hearing voices, one or several, typically making commentaries about the individual or conversing with each other.  One word… WOW.  Persecutory, grandiose, or somatic delusions are most common.  The first person accounts depict individuals who are very disturbed to say the least.  In particular, an individual who believed that they were controlled by someone (the “controller”) and the persistent belief that other people have external controllers was beyond comprehension.

Regarding the etiology of the disorder, it is increasingly evident that there is some kind of genetic link involved in schizophrenia.  The diathesis-stress theory of illness is the predominant theory, suggesting that a predisposition may not be sufficient in itself to cause schizophrenia, but probably requires some kind of “trigger” such as exposure to prenatal insults.  (Blaney & Millon, 2009, p. 302)

This is my first exposure to “genotype” and “phenotype.”  Genotype represents the underlying genetic constitution of the individual (genetic predisposition?).  Phenotype refers to the observable traits, characteristics, or behaviors of an individual.  It is entirely possible to have a genotype that suggests a predisposition to a disorder like schizophrenia, but the disorder will not be expressed behaviorally by the phenotype.  “In other words, what the individual inherits is a liability or predisposition for developing the disease, not the disease itself.”  (Blaney & Millon, 2009, p. 305)

With regard to prenatal and perinatal insult, the critical period of exposure appears to be the 2nd trimester (4th-6th month of pregnancy).  Examples might include toxemia, preeclampsia, or labor delivery complications.  Fetal hypoxia (oxygen deprivation) was strongly linked with later schizophrenia.  Prenatal stress, inclining losing a spouse or being exposed to a military invasion, has been implicated in the predisposition of schizophrenia.  Maternal viral infection, including influenza, was also implicated.  Unlike influenza studies, increased risk for offspring exposed to prenatal nutritional deficiencies was primarily attributed to growth and development during the 1st trimester, not the second.

Cognitive impairments are considered to be central, or primary, in schizophrenia.  Typically, they predate the more typical outward signs of the illness (hallucinations, delusions, etc.).  The cognitive impairments can occur in the absence of the other clinical symptoms.  “It is estimated that 90% of patients have clinically meaningful deficits in at least one cognitive domain and that 75% have deficits in at least two.”  (Blaney & Millon, 2009, p. 309)

Neurocognitive assessment is used in contemporary practices to quantify the severity of impairment in clinically relevant domains of cognitive functioning.  Relevant domains are speed of processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning and problem solving, and social cognition.  Typically, a patient with schizophrenia will struggle with verbal learning and vigilance, and have lesser impairments in visual organization and vocabulary.

A neuro-developmental view of schizophrenia is the foundation of high-risk research.  “The majority of individuals who succumb to schizophrenia and other psychotic disorders manifest prodromal signs of behavioral disturbance” in adolescence, and they get progressively worse as they approach young adulthood.  (Blaney & Millon, 2009, p. 321)  The prodromal period represents a clinically significant opportunity for intervention, with high potential to shed light on the etiological origins of schizophrenia.
