Understanding Suicidal Thoughts

Suicidal ideation refers to thoughts about self-harm and ending one’s life. Individuals with suicidal ideation may think about, contemplate, or plan suicide. ^[1]

There are varying degrees or levels of suicidal thoughts. For example, this can range from infrequent, general thoughts about wanting to die but with no specific plan, all the way to very frequent, intense, and specific plans for suicide with an established intent to carry the plan out. ^[1]

In addition, many individuals with suicidal ideation may show other signs and symptoms too, such as: ^[2]

• Feeling disconnected from others
• Withdrawing or isolating from friends and family
• Feeling trapped, hopeless, or helpless
• Feeling guilty or like a burden to others
• Thinking that people would be better off without them
• Thinking, talking, or posting a lot about death, dying, or violence

How Common is It?

In the United States, recent estimates from 2024 have shown that over 14 million adults (around 5.5%) aged 18 and over had serious thoughts of suicide. Of these, 4.6 million made suicide plans. Among adults, suicidal thoughts are most common in individuals aged 18-25, with a prevalence of over 12% in this population. ^[3]

Suicidal ideation is even more common in children and adolescents. 18% of young people will experience suicidal ideation at some point. ^[4]

Passive vs Active Suicidal Ideation

Suicidal ideation exists on a spectrum. Passive suicidal ideation represents the midler end of this spectrum, characterized by non-specific thoughts about suicide or self-harm that may come and go, but with no real intent or specific plan. Contrarily, active suicidal ideation represents a more severe form of suicidal ideation because it involves detailed plans and an intent to act on those plans. ^[1]

Conditions Associated with Suicidal Ideation

Suicidal ideation is associated with many conditions, including both mental and physical conditions. Some of the most common conditions associated with suicidal ideation are: ^[1]

• Depression
• Bipolar disorder
• Schizophrenia and related disorders
• Substance use disorders
• Epilepsy
• Traumatic brain injury (TBI)

In fact, these above conditions increase the risk of suicide by more than 3-fold. Beyond these, suicidal ideation is also common in individuals with chronic pain, cancer, or other chronic health conditions. ^[1]

Suicidal Ideation Without a Diagnosed Condition

Suicidal ideation can also occur without a diagnosed condition too. In general, suicidal ideation is more likely to happen during periods of higher life stress, such as: ^[5]

• Getting fired from a job
• The death of a loved one
• Break-ups, divorce, or other intense relationship issues

Causes of Suicidal Ideation

There are many possible causes of suicidal ideation, including genetic, biological, environmental, and situational factors. Several theories also help to explain the cause and development of suicidal ideation, such as:

• Stress-diathesis models: These models argue that suicidal ideation is most likely to occur when life stressors exceed someone’s perceived ability to cope with them. ^[1]

• Interpersonal theory (IPT): The IPT of suicide explains that suicidal thoughts develop when someone perceives they are a burden and that they feel they don’t belong. ^{[1] [6]}

• Integrated motivational-volitional (IMV) model: The IMV model of suicidal behavior explains that various factors increase the risk of suicidal thoughts, such as defeat, feeling trapped, or lack of social support. ^[6]

There are also several identified biological and genetic factors that increase the risk of suicidal ideation, such as: ^[1]

• Hypothalamic-pituitary-adrenal (HPA) axis dysfunction, which results in higher stress
• Brain inflammation
• Immune system dysfunction
• Certain genes (indicating that family history plays a role)

Other risk factors and possible causes of suicidal ideation include: ^{[5] [6]}

• Past suicide attempts
• Social isolation or loneliness
• Mental health disorders
• Being LGBT without a supportive family
• Substance use problems
• Bullying
• Feeling that you don’t belong
• Feeling worthless or hopeless
• Feeling trapped or helpless

Complications and Risks

One of the most prominent complications and risks of suicidal ideation is actual suicide attempts. In fact, about 1 in 7 people who have suicidal ideation will go on to make a suicide attempt. ^{[1] [3]}

Even when the attempts are unsuccessful, this often leads to many consequences, such as severe or permanent physical damages, and distress to the individual and those who love them. Actual death from suicide can lead to substantial grief, guilt, anger, and depression for those who are left behind. ^[5]

Suicidal ideation can also greatly diminish life quality, overall health, and ability to function. Suicidal thoughts often contribute to: ^{[1] [5]}

• Significant emotional distress
• Impaired relationships
• Difficulty performing daily obligations, such as at work or school or in the home
• Isolation, loneliness, and despair
• Worsening of existing mental health conditions (e.g. depression, anxiety, PTSD)
• Physical health problems (e.g. decreased immune function, cardiovascular issues, or gastrointestinal complaints)

Many individuals with suicidal ideation may also turn to alcohol or other substances to cope, which may increase the risk of addiction. ^[1]

Diagnosing Suicidal Ideation

Diagnosing suicidal ideation requires a comprehensive evaluation. Typically, individuals first meet with their regular doctor, who will go over all relevant history, such as medical and family history, as well as any identified risk factors. ^[1]

After this, suicidal risk and suicidal ideation are assessed through a psychiatric evaluation with a mental health professional, which commonly includes a clinical interview to gain an in-depth understanding of the individual’s concerns. This is also paired with common tools for evaluating suicidal ideation such as:

• Beck Scale for Suicidal Ideation: This scale includes 21 items that measure the intensity of suicidal thoughts from multiple dimensions. ^[1]
• Suicidal Ideation Attributes Scale: This scale consists of 5 items that measure the presence, frequency, and intensity/overall distress of suicidal thoughts. ^[1]
• Ask-Suicide Screening Questions Toolkit: This toolkit consists of four brief questions to assess suicide risk, which then leads to further evaluation as deemed necessary. ^[7]
• Columbia-Suicide Severity Rating Scale: This scale assesses the severity and urgency of suicidal thoughts, suicidal behaviors, and the potential lethality of the attempts. It is used for cases requiring urgent intervention. ^[1]

The psychiatric evaluation is also used to assess any other mental health conditions or neurological disorders. This helps provide the most appropriate treatment plan, if needed.

Treatment for Suicidal Ideation

Given the significant potential for harm and distress, treatment for suicidal ideation is highly important. The exact treatments vary depending on the severity of the issues, but may include:

• Medication
• Psychotherapy
• Inpatient treatment

Medication

A variety of medications may be helpful for suicidal ideation. Medications may help by treating any underlying mental health conditions or neurobiological factors that are contributing to suicidal ideation symptoms. Examples of medications that may be used are: ^{[1] [8]}

• Antidepressants: Selective-serotonin reuptake inhibitors (SSRIs) and other antidepressant may help reduce suicidal thoughts and behaviors, while possibly helping with depression.
• Ketamine: When used in a clinical context, ketamine may be particularly helpful for quickly reducing suicidal ideation, and helping those with depression.
• Lithium: This is particularly used for suicidal ideation in individuals with bipolar disorder and some other mood disorders.
• Antipsychotics: Clozapine or other antipsychotics may help with suicidal thoughts in individuals with schizophrenia or schizoaffective disorder.

Psychotherapy

Psychotherapy may help with suicidal ideation by modifying problematic thought patterns, beliefs, or self-regulation strategies. Common psychotherapies for suicidal ideation are cognitive-behavioral therapy (CBT) and dialectical behavioral therapy (DBT).

CBT helps individuals understand the connections between their thoughts, beliefs, and behaviors. For individuals with suicidal ideation, it may help them form more rational, helpful beliefs about themselves and their situation, while also helping with self-confidence, emotional regulation, and stress management. ^[1]

DBT incorporates elements of CBT, as well as skills training and mindfulness techniques. In turn, DBT may help with emotional regulation, distress tolerance, and interpersonal functioning, all of which may mitigate suicidal thoughts and related symptoms. ^[1]

Inpatient Treatment

Severe cases of suicidal ideation may require inpatient treatment, especially when there is an immediate risk of harm to oneself or others. Inpatient treatment typically consists of medication and psychotherapy, with regular monitoring of the patient’s symptoms and overall progress. Patients are able to leave once the doctors determine that the treatments are working and that the patient is at a low-enough risk state. Follow-ups and regular outpatient monitoring are often used to ensure long-term success.

Managing Suicidal Ideation Long-Term

Having a history of suicidal ideation is the greatest risk factor for experiencing suicidal ideation in the future. Therefore, it’s important to incorporate management strategies on a regular basis in order to reduce this risk and promote long-term mental well-being. Such strategies include:

• Regular mental health check-ups
• Stress-management, such as through meditation, yoga, or deep breathing
• Avoiding substance use
• Certain lifestyle strategies, such as a healthy diet and regular exercise
• Journaling/recording to help monitor symptoms and identify triggers
• Spending time with family, friends, and other important individuals

Social Support

Adequate social support is essential for helping with suicidal ideationa and promoting long-term mental wellness. Be open and honest with trusted family and friends about your concerns and issues. It can be tempting to withdraw or isolate yourself, but people are there to help.

Support groups can also be very valuable, especially if you don’t have many trusted family members or friends. These groups often meet on a regular basis, and can be a great way to build quality connections.

Takeaway

Suicidal ideation is a symptom of significant mental distress, and requires proper attention. While you may feel that you will never break out of your suicidal thoughts, the right treatment and support can lead to significant improvements and long-lasting mental wellness.

If you’re dealing with suicidal ideation and don’t know what to do, seek out professional mental help as soon as possible. They can help you get started on a path towards newfound mental well-being.
