Understanding False Beliefs, Suspicious Thoughts & When to Seek Professional Help
Delusions are strongly held beliefs that remain fixed even when there is clear evidence that the belief may not be accurate. They can occur as part of different mental health conditions, neurological conditions, substance-related problems, or other medical conditions. A proper psychiatric assessment is important to understand the underlying cause.
At Kosha Mind Care Clinic, Borivali West, Mumbai, Dr. Shraddha Soni (MBBS, M.D. Psychiatry, FIPS) provides compassionate, patient-centred psychiatric care for individuals experiencing delusions, suspiciousness, unusual beliefs, and other mental health concerns.
What Are Delusions?
A delusion is a firmly held belief that is not supported by available evidence and generally does not change even when reasonable evidence challenges it. Delusions can sometimes appear realistic or possible, which can make them difficult for family members to recognise as a mental health symptom.
For example, a person may strongly believe that someone is following them, monitoring them, trying to harm them, or being unfaithful despite a lack of reliable evidence.
Delusions can occur on their own or alongside other symptoms such as hallucinations, confused thinking, unusual behaviour, or difficulty distinguishing reality from perception.
Common Types of Delusions
Delusions can take different forms depending on the person’s experiences and underlying condition.
Persecutory Delusions
The person may believe that others are following, spying on, threatening, poisoning, or plotting against them.
Jealous Delusions
A person may firmly believe that their partner or spouse is unfaithful despite a lack of supporting evidence.
Grandiose Delusions
The person may believe they possess exceptional abilities, importance, wealth, power, or a special role.
Somatic Delusions
These involve strongly held beliefs about the body or health that are not supported by appropriate medical evidence.
Erotomanic Delusions
The person may believe that another individual, sometimes someone they have little or no actual relationship with, is in love with them.
These are recognised forms of delusional disorder, although delusions can also occur in other psychiatric conditions.
Signs That May Occur With Delusions
A person experiencing delusions may:
- Become unusually suspicious of others
- Frequently accuse family members or friends
- Believe they are being watched or followed
- Misinterpret ordinary events or conversations
- Become increasingly distrustful
- Repeatedly seek reassurance or evidence
- Withdraw from family or social situations
- Have difficulty accepting alternative explanations
- Experience anxiety or fear
- Show changes in behaviour or communication
Delusions may also occur with hallucinations, disorganised speech, changes in sleep, social withdrawal, or difficulty functioning, particularly when they are part of psychosis.
What Causes Delusions?
There is not always one single cause. Delusions may occur as part of several psychiatric or medical conditions.
Possible causes and associated conditions include:
Psychotic Disorders
Delusions can occur in conditions such as schizophrenia and other psychotic disorders.
Bipolar Disorder
Psychosis, including delusions, can sometimes occur during severe mood episodes.
Severe Depression
Some people with severe depression may experience psychotic symptoms.
Dementia and Neurological Conditions
Psychotic symptoms can occur in some older adults with conditions such as Alzheimer’s disease, Parkinson’s disease, and related neurological disorders.
Substance or Medication-Related Causes
Certain drugs, alcohol or other substances, and some prescription medications may contribute to psychotic symptoms.
Other Medical Conditions
A psychiatric evaluation may include consideration of physical or neurological causes, particularly when symptoms appear suddenly or for the first time later in life.
Delusions vs Suspiciousness
Being cautious or suspicious does not necessarily mean that a person has delusions.
The important difference is often the strength and persistence of the belief. A delusional belief can remain firmly held despite clear evidence to the contrary.
A psychiatrist can assess the person’s thoughts, behaviour, medical history, medications, substance use, and other symptoms to understand what may be happening.
When Should You Consult a Psychiatrist?
Professional assessment may be appropriate when a person:
- Has persistent suspicious or unusual beliefs
- Believes others are trying to harm or monitor them
- Frequently accuses family members without evidence
- Has significant changes in behaviour or personality
- Becomes increasingly isolated
- Has difficulty distinguishing reality from beliefs or perceptions
- Experiences hallucinations along with unusual beliefs
- Has difficulty managing work, studies, relationships, or daily activities
- Shows sudden or severe changes in thinking or behaviour
Early assessment can help identify the possible cause and allow appropriate treatment to begin. NIMH notes that timely treatment of psychotic symptoms is important and that untreated symptoms can affect relationships and daily functioning.
Diagnosis and Psychiatric Assessment for Delusions
There is no single test used to diagnose every case of delusion. A psychiatrist generally considers the person’s symptoms, history, behaviour, functioning, and the duration and nature of the beliefs.
The assessment may include:
Detailed Clinical History
The psychiatrist may ask about when the symptoms began, how they have changed, and how they affect everyday life.
Mental Health Assessment
Other symptoms such as hallucinations, mood changes, anxiety, sleep problems, or disorganised thinking may also be assessed.
Medical and Medication History
Physical health conditions and prescribed medicines can sometimes contribute to changes in thinking or perception.
Substance Use Assessment
Alcohol and other substances can contribute to psychotic symptoms, so this may be considered during evaluation.
Further Medical Investigation
Depending on the person’s age, symptoms, and clinical history, additional medical investigations may be recommended to rule out other causes.
Delusion Treatment in Borivali West
Treatment depends on the underlying cause, the symptoms involved, and the individual’s overall health.
At Kosha Mind Care Clinic, the treatment plan is personalised according to the individual’s needs.
Psychiatric Evaluation
A detailed psychiatric assessment helps identify the nature of the beliefs and determine whether they may be associated with a psychiatric, neurological, medical, or substance-related condition.
Medication Management
Antipsychotic medicines are commonly used to treat psychotic symptoms, including delusions, when clinically appropriate. The choice of medication and dosage depends on the individual’s condition and should be determined and monitored by a qualified psychiatrist.
Psychological Support
Depending on the condition, psychological interventions may form part of the overall treatment plan. Building a trusting therapeutic relationship can be particularly important when a person has limited insight into their symptoms.
Family Guidance
Family members may need guidance on how to communicate with someone experiencing fixed or suspicious beliefs without unnecessarily escalating conflict.
Regular Follow-Up
Ongoing psychiatric follow-up can help monitor symptoms, treatment response, medication-related concerns, and changes in daily functioning.
How Can Family Members Support Someone With Delusions?
It can be difficult when someone strongly believes something that family members know is not true.
Family members can try to:
- Remain calm and respectful
- Avoid arguing aggressively about the belief
- Listen to the person’s concerns
- Avoid reinforcing the delusion as a fact
- Encourage professional psychiatric assessment
- Monitor significant changes in behaviour
- Maintain a safe and supportive environment
- Follow the treating psychiatrist’s recommendations
If there is an immediate risk of harm to the person or someone else, seek emergency medical assistance rather than trying to manage the situation alone.

For individuals experiencing unusual beliefs, suspiciousness, behavioural changes, or other symptoms associated with psychosis, a professional psychiatric evaluation can help identify the appropriate course of care.
Why Professional Assessment Matters
Delusions can sometimes be a symptom of an underlying psychiatric or medical condition. They should not automatically be assumed to indicate one particular diagnosis.
A psychiatrist can assess the complete clinical picture and determine whether the symptoms are related to a psychotic disorder, mood disorder, dementia, substance use, medication, or another medical condition.
Seeking professional help early can also help address symptoms before they significantly affect relationships, work, studies, or everyday functioning.
Frequently Asked Questions
What are delusions?
Delusions are firmly held beliefs that remain fixed despite clear evidence that contradicts them. They can occur in several psychiatric and medical conditions.
Are delusions a mental illness?
A delusion is a symptom, not necessarily a diagnosis by itself. Delusions can occur in conditions such as delusional disorder, schizophrenia, bipolar disorder, severe depression, dementia, and some medical or substance-related conditions.
Can delusions be treated?
Treatment depends on the underlying cause. Psychiatric treatment may include medication, psychological support, family education, and regular follow-up. Antipsychotic medicines may be used when clinically appropriate.
Should you argue with someone experiencing delusions?
Aggressive arguments may increase distress or conflict. It is generally more helpful to remain calm, listen to their concerns, avoid validating the belief as fact, and encourage professional help.
Can elderly people develop delusions?
Yes. Psychotic symptoms can occur in older adults and may sometimes be associated with neurological conditions such as Alzheimer’s disease or Parkinson’s disease, among other causes. A medical and psychiatric assessment is important, particularly when symptoms appear for the first time later in life.
When should I consult a psychiatrist for delusions in Borivali?
If unusual or fixed beliefs are persistent, affecting relationships or daily functioning, causing significant distress, or accompanied by hallucinations, behavioural changes, or safety concerns, a psychiatric assessment is appropriate.
