Mental Disorders
What is Mental Disorders?
Mental disorders are conditions that affect your mood, thinking, and behavior. They include depression, anxiety, bipolar disorder, schizophrenia, and many other diagnoses. These conditions impact how you feel, relate to others, and function in daily life.
Mental health is influenced by brain chemistry, genetics, life experiences, and environmental factors. Your body needs specific nutrients and a healthy internal environment for your brain to work well. Deficiencies in omega-3 fatty acids like EPA or exposure to toxic metals like mercury can contribute to mental health symptoms.
Root-cause approaches look at the whole picture of your health. This includes nutrition, inflammation, hormone balance, and environmental exposures. Addressing these underlying factors can support better mental health alongside traditional treatments.
Symptoms
- Persistent sadness, hopelessness, or empty mood
- Loss of interest in activities you once enjoyed
- Excessive worry, fear, or nervousness
- Changes in sleep patterns, either too much or too little
- Fatigue or low energy that does not improve with rest
- Difficulty concentrating, making decisions, or remembering things
- Changes in appetite or weight
- Irritability, anger, or restlessness
- Physical symptoms like headaches or stomach problems without clear cause
- Thoughts of death or self-harm
Some people experience subtle symptoms that develop slowly over time. Others may not recognize their symptoms as part of a mental health condition. Early detection and treatment lead to better outcomes.

Causes and risk factors
Mental disorders develop from a combination of genetic, biological, environmental, and psychological factors. Family history increases risk, but lifestyle and environment also play important roles. Brain chemistry imbalances involving neurotransmitters like serotonin and dopamine affect mood and thinking. Chronic stress, trauma, and major life changes can trigger or worsen symptoms.
Nutritional deficiencies can impact mental health significantly. Low levels of omega-3 fatty acids like EPA are linked to depression and other mood disorders. Environmental toxins like mercury damage the nervous system and can contribute to anxiety, depression, and cognitive problems. Chronic inflammation, poor gut health, hormone imbalances, and vitamin deficiencies may also affect brain function. Substance use, lack of sleep, and social isolation are additional risk factors.
How it's diagnosed
Mental disorders are typically diagnosed through a combination of clinical interviews, questionnaires, and assessment of symptoms. A healthcare provider will ask about your mood, thoughts, behaviors, and how symptoms affect your daily life. They may also review your medical history, medications, and family history.
Blood tests can identify underlying factors that contribute to mental health symptoms. Testing for omega-3 fatty acids like EPA helps reveal nutritional deficiencies that may worsen depression and anxiety. Blood mercury levels can detect toxic metal exposure that affects brain function and mood. Rite Aid offers add-on testing for EPA and mercury through our network of Quest Diagnostics locations. These tests provide valuable information about root causes that may be contributing to your symptoms.
Treatment options
- Increase omega-3 fatty acids through fatty fish like salmon, mackerel, and sardines, or through high-quality fish oil supplements
- Reduce exposure to mercury by limiting high-mercury fish like tuna, swordfish, and king mackerel
- Eat a nutrient-dense diet rich in vegetables, fruits, whole grains, and lean proteins
- Exercise regularly, aiming for at least 30 minutes most days of the week
- Prioritize sleep with consistent bedtime routines and 7 to 9 hours nightly
- Practice stress management through meditation, deep breathing, or yoga
- Build strong social connections and seek support from friends, family, or support groups
- Limit alcohol and avoid recreational drugs
- Consider therapy such as cognitive behavioral therapy or other evidence-based approaches
- Work with a healthcare provider about medications like SSRIs, SNRIs, or mood stabilizers if needed

Frequently asked questions
Blood tests cannot diagnose mental disorders directly, but they can identify contributing factors. Tests for omega-3 fatty acids like EPA reveal nutritional deficiencies linked to depression and anxiety. Blood mercury testing detects toxic exposures that damage the nervous system. These results help guide treatment by addressing root causes.
EPA is an omega-3 fatty acid that supports brain health and reduces inflammation. Low EPA levels are associated with depression, schizophrenia, and other mental disorders. Your brain needs adequate omega-3s to produce neurotransmitters and maintain healthy cell membranes. Increasing EPA through diet or supplements may improve mood and cognitive function.
Mercury is a toxic metal that damages the nervous system and brain. Chronic exposure can cause depression, anxiety, mood swings, and cognitive problems. Mercury interferes with neurotransmitter function and increases oxidative stress in the brain. Reducing exposure and testing blood levels can help identify if mercury is contributing to mental health symptoms.
The most common mental disorders include depression, anxiety disorders, and post-traumatic stress disorder. Bipolar disorder, obsessive-compulsive disorder, and schizophrenia are also significant conditions. Many people experience more than one mental health condition at the same time. Early treatment improves quality of life for all of these conditions.
See a doctor if symptoms persist for more than two weeks or interfere with daily life. Seek immediate help if you have thoughts of harming yourself or others. Any symptoms that affect your work, relationships, or ability to care for yourself deserve professional attention. Early intervention leads to better outcomes and faster recovery.
Yes, diet and lifestyle have significant impacts on mental health. Regular exercise reduces symptoms of depression and anxiety as effectively as some medications. Eating omega-3-rich foods, getting enough sleep, and managing stress all support brain health. These changes work best when combined with professional treatment for moderate to severe conditions.
Fatty fish like salmon and sardines provide omega-3s that support brain function. Leafy greens, berries, nuts, and whole grains offer vitamins and antioxidants. Fermented foods like yogurt and kimchi support gut health, which connects to mental health. Limiting processed foods, sugar, and alcohol also helps stabilize mood.
Treatment duration varies based on the condition and individual factors. Some people notice improvement within a few weeks of starting medication or therapy. Others need months or years of ongoing treatment to manage chronic conditions. Addressing nutritional deficiencies and environmental toxins may show benefits in weeks to months.
Mental disorders often run in families, suggesting a genetic component. However, genes are not destiny. Environmental factors, nutrition, stress, and lifestyle all influence whether someone develops a mental health condition. Having a family history increases risk but does not guarantee you will develop the same condition.
While you cannot prevent all mental disorders, you can reduce your risk. Maintain a healthy diet rich in omega-3s and low in toxins like mercury. Exercise regularly, manage stress, and prioritize sleep. Build strong social connections and seek help early if symptoms develop. These habits support resilience and overall mental health.
