What are the warning signs of bipolar depression in a 19 y/o?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

What were the first signs that someone at 19 might miss before a bipolar diagnosis? My younger sister is 19, and we only found out last month that she has bipolar depression after a severe episode that landed her in the hospital. Looking back, she experienced months of insomnia, spent all her savings, and then crashed into a deep depression where she would not leave her room.

We just thought it was stress from college, but her psychiatrist mentioned that these were classic early signs we all overlooked. Now, her lithium levels are being monitored, and she is on Lamotrigine. Could you please tell us which early warning signs families usually miss so we can identify future episodes more quickly? We want to be prepared so we do not have to go through that again.

Please guide.

Hello,

Welcome to icliniq.com.

I understand your concern.

Bipolar disorder is characterized by intense and fluctuating mood episodes, ranging from extreme highs, known as mania or hypomania, to severe lows, referred to as depression (a mood disorder that causes a persistent feeling of sadness and loss of interest).

This disorder can significantly disrupt energy levels, daily functioning, and overall quality of life. Understanding the two primary poles of bipolar disorder, mania and depression, is crucial for effective management.

Early signs of a manic episode may include:

  1. A decreased need for sleep or sleeping less than usual.

  2. Racing thoughts can make it difficult to concentrate.

  3. Increased spending or engaging in spree buying can lead to financial problems.

  4. An unusually elevated mood, which may also manifest as irritability.

  5. Overindulgence in substance use or recreational activities.

  6. Talking more than usual or feeling a strong urge to communicate.

On the other hand, a depressive episode is characterized by:

  1. Persistent fatigue or a feeling of low energy that makes even simple tasks feel overwhelming.

  2. Frequent physical complaints, such as headaches or stomach issues, without any clear medical cause.

  3. Heightened anxiety that can worsen feelings of sadness or hopelessness.

  4. Difficulty concentrating or making decisions.

  5. Sleep disturbances, including insomnia or excessive sleepiness.

Several major factors can trigger breakthrough episodes, such as:

  1. Sleep deprivation can destabilize mood.

  2. Stressful life events, including job loss or significant conflicts within relationships or family.

  3. Financial difficulties contribute to anxiety.

  4. Substance use, including alcohol or drugs, can exacerbate symptoms.

Recognizing these signs and triggers is essential for individuals living with bipolar disorder and their loved ones. Early identification allows for timely intervention and management strategies, helping maintain mood stability and improve overall well-being.

Treatment options may include therapy, medication, and support from mental health professionals, all of which play an essential role in managing this complex condition effectively.

I hope you find this information helpful.

Thank you for reaching out.
