Mental illnesses that cause irrational thoughts include Obsessive-Compulsive Disorder (OCD) (unwanted obsessions), Schizophrenia (psychosis, delusions, paranoia), Delusional Disorder, certain Anxiety Disorders, and some Personality Disorders, all characterized by intrusive, illogical beliefs or thought patterns that significantly disrupt daily life, such as fears of contamination (OCD) or persecutory beliefs (paranoia/delusional disorder).
Irrational thoughts are unrealistic, exaggerated, or fear-driven beliefs that distort reality and fuel anxiety. They often stem from an individual's inclination to overestimate potential risks and dangers. While this can happen to anyone, people struggling with anxiety disorder are prone to irrational thinking.
Common signs and symptoms include:
Obsessive-Compulsive Disorder: When Unwanted Thoughts or Repetitive Behaviors Take Over - National Institute of Mental Health (NIMH)
TAC's definition of severe mental illness includes schizophrenia, schizoaffective disorder, schizophreniform disorder, bipolar I disorder, and major depression with psychotic features. These disorders often include psychosis as a component.
Psychotic disorders include schizophrenia, schizoaffective disorder, schizophreniform disorder, brief psychotic disorder, delusional disorder, shared psychotic disorder, substance-induced psychotic disorder, and paraphrenia.
Background: People who have an obsessive-compulsive disorder (OCD) tend to manifest a need for excessive control over their partners and other relatives, which then constitutes a principal problem in their relationships. This behaviour probably relates to an unmet need for safety in their childhood.
The 15-Minute Rule for OCD is a Cognitive Behavioral Therapy (CBT) technique where you delay performing a compulsion for 15 minutes when an obsessive thought triggers anxiety, allowing the urge to lessen naturally as you practice exposure and response prevention (ERP). It teaches your brain that discomfort decreases without the ritual, building resilience and breaking the obsessive-compulsive cycle by gradually increasing tolerance for uncertainty and distressing feelings.
OCD can affect men, women and children. People can start having symptoms from as early as 6 years old, but it often begins around puberty and early adulthood. OCD can be distressing and significantly interfere with your life, but treatment can help you keep it under control.
Five significant signs your brain might be in trouble include memory loss (especially recent events), difficulty with familiar tasks or language, confusion about time/place, significant personality/behavior changes, and problems with judgment, focus, or coordinating movement, often indicating conditions like dementia, brain injury, or other neurological issues, requiring a doctor's visit.
Crippling anxiety is one of the hallmark signs of a nervous breakdown. It goes beyond everyday stress and can include persistent worry, panic attacks or an overwhelming sense of dread. This level of anxiety can interfere with daily activities and decision-making.
Starting in your 60s, you may notice normal cognitive aging when your brain's processing speed slows down. You may not readily recall the name of a childhood friend or forget where you parked the car.
The first stage of a mental breakdown, often starting subtly, involves feeling overwhelmed, exhausted, and increasingly anxious or irritable, coupled with difficulty concentrating, changes in sleep/appetite, and withdrawing from activities or people that once brought joy, all stemming from intense stress that becomes too much to handle.
Five key warning signs of mental illness include significant mood changes (extreme highs/lows, persistent sadness), withdrawal from friends/activities, major changes in sleep or eating habits, difficulty coping with daily problems or stress, and thoughts of self-harm or suicide, alongside other indicators like substance abuse, confusion, or changes in hygiene. These signs often represent a noticeable shift in behavior, functioning, and emotional state that impacts daily life.
Also known as cognitive distortions, irrational thoughts are patterns of thinking that are illogical or not based on reality. These thoughts often stem from ingrained beliefs or cognitive biases and can lead to negative emotions and behaviors.
The great toll untreated OCD takes
Living in a constant state of anxiety is not healthy. It is not uncommon for people with OCD to suffer from other mental health problems, like depression, as a result of their OCD symptoms. People with OCD may isolate themselves, and prefer to be alone.
Common types of compulsive behaviour in people with OCD include:
In addition to a total score, the OCBQ contains 6 specific belief domains hypothesized to be related to OCD. These are responsibility for harm, controllability of thoughts, overestimation of risk, need for certainty, beliefs about discomfort/anxiety, and beliefs about one's ability to cope.
An OCD attack can feel like a storm of intense emotions and physical sensations. The person may experience physical symptoms, such as sweating, shaking, and rapid heartbeat. These symptoms may be accompanied with obsessive thoughts, intrusive thoughts, and an urge to engage in compulsions.
Among all the personality disorders, obsessive-compulsive personality disorder (OCPD) is perhaps most commonly linked with OCD.
The main medicines prescribed are a type of antidepressant called selective serotonin reuptake inhibitors (SSRIs). An SSRI can help improve OCD symptoms by increasing the levels of a chemical called serotonin in your brain. You may need to take an SSRI for up to 12 weeks before you notice any benefit.
The acute stage is marked by the emergence of full-blown psychotic symptoms, often causing significant disruption to the individual's life. Key symptoms include. Audio and visual hallucinations (seeing or hearing things that aren't there) and in some cases tactile hallucinations (feeling things that aren't there)
In cases of hyperactive delirium, symptoms are often mistaken for those of a psychosis—typically schizophrenia or mania. In hypoactive cases of delirium, symptoms may lead to a misdiagnosis of severe depression.
Schizotypal personality disorder (SPD) is a mental condition in which a person has trouble with relationships and disturbances in thought patterns, appearance, and behavior.
