BPD is a very different diagnosis than schizophrenia, though the two can co-exist. While BPD is characterized by a pattern of instability in interpersonal relationships; schizophrenia is characterized by a range of cognitive, behavioral, and emotional dysfunctions.
The study's main finding is that in a sample of 30 clinically diagnosed BPD patients, the vast majority of patients met criteria for a schizophrenia spectrum disorder, i.e., SPD or schizophrenia (67% in DSM-5 vs. 77% in ICD-10).
Although borderline personality disorder (BPD) and schizophrenia (SZ) are notably different mental disorders, they share problems in social cognition—or understanding the feelings, intentions and thoughts of other people.
A major difference between the psychosis characteristic of normal bipolar disorder and schizoaffective disorder is that bipolar symptoms will remit when the mood disorder episode is over.
For example, in one study, 24% of BPD patients reported severe psychotic symptoms and about 75% had dissociative experiences and paranoid ideation. Thus, we start with an overview regarding the prevalence of psychotic symptoms in BPD patients.
In particular, there is evidence that BPD is commonly misdiagnosed as Bipolar Disorder, Type 2. One study showed that 40% of people who met criteria for BPD but not for bipolar disorder were nevertheless misdiagnosed with Bipolar Type 2.
But research from 2018 illustrated that schizophrenia was present in only 2% of females with BPD.
You could have: Hallucinations: Seeing or hearing things that aren't there. Delusions: Mistaken but firmly held beliefs that are easy to prove wrong, like thinking you have superpowers, are a famous person, or people are out to get you. Disorganized speech: Using words and sentences that don't make sense to others.
Between 50% and 90% of patients with BPD report hearing voices that other people do not hear (Yee et al., 2005; Kingdon et al., 2010). Importantly, such auditory verbal hallucinations (AVH) are a risk factor for suicide plans, attempts, and hospitalization (Miller et al., 1993; Zonnenberg et al., 2016).
The Social Security Administration placed borderline personality disorder as one of the mental health disorders on its disabilities list. However, you'll have to meet specific criteria for an official disability finding. For example, you must prove that you have the symptoms of the condition.
Bipolar disorder.
Some people with severe bipolar disorder have delusions or hallucinations. That's why they may be misdiagnosed with schizophrenia.
Schizophrenia can be hard to diagnose for a few reasons. One is that people with the disorder often don't realize they're ill, so they're unlikely to go to a doctor for help. Another issue is that many of the changes leading up to schizophrenia, called the prodrome, can mirror other normal life changes.
The patients in the current study experienced psychotic symptoms lasting between three weeks and four months. They were characterized by hysterical features, visual disturbances, and a possible history of sexual trauma. The diagnostic and therapeutic implications of these prolonged psychotic episodes is discussed.
Borderline personality disorder is a mental illness that severely impacts a person's ability to regulate their emotions. This loss of emotional control can increase impulsivity, affect how a person feels about themselves, and negatively impact their relationships with others.
Common symptoms of schizophrenia
You may be diagnosed with schizophrenia if you experience 2 or more of the following symptoms for at least 1 month: delusions. hallucinations. incoherent speech, or speech that quickly switches from topic to topic with no thread between them.
In most people with schizophrenia, symptoms generally start in the mid- to late 20s, though it can start later, up to the mid-30s. Schizophrenia is considered early onset when it starts before the age of 18. Onset of schizophrenia in children younger than age 13 is extremely rare.
When stressed, people with borderline personality disorder may develop psychotic-like symptoms. They experience a distortion of their perceptions or beliefs rather than a distinct break with reality. Especially in close relationships, they tend to misinterpret or amplify what other people feel about them.
With borderline personality disorder, you have an intense fear of abandonment or instability, and you may have difficulty tolerating being alone. Yet inappropriate anger, impulsiveness and frequent mood swings may push others away, even though you want to have loving and lasting relationships.
Firstly, it was established that a significant number of BPD patients experiences various kinds of hallucinations - auditory, visual hallucinations, even olfactory and tactile. Other psychotic symptoms (such as ideas of reference, delusions, thought insertion) were also reported.
Residual schizophrenia is the mildest form of schizophrenia characteristic when positive symptoms of paranoid schizophrenia (hallucinations, delusional thinking) are not actively displayed in a patient although they will still be displaying negative symptoms (no expression of emotions, strange speech).
Schizophrenia usually involves delusions (false beliefs), hallucinations (seeing or hearing things that don't exist), unusual physical behavior, and disorganized thinking and speech. It is common for people with schizophrenia to have paranoid thoughts or hear voices.
Catatonic schizophrenia
This is the rarest schizophrenia diagnosis, characterised by unusual, limited and sudden movements.
People with BPD do not generally have manic episodes. They vary from feeling loving and secure in their relationship to depressed, angry, or lonely. However, both people with BPD and people with bipolar disorder can be at risk for self-harm and impulsive behaviors.
Separations, disagreements, and rejections—real or perceived—are the most common triggers for symptoms. A person with BPD is highly sensitive to abandonment and being alone, which brings about intense feelings of anger, fear, suicidal thoughts and self-harm, and very impulsive decisions.
The symptoms of borderline personality disorder usually first occur in the teenage years and early twenties. However, onset may occur in some adults after the age of thirty, and behavioral precursors are evident in some children.
