The research showed that the six biotypes of depression affect different brain circuits. These circuits are involved in emotions, motivation, and thinking. Knowing these differences is key to making better treatments.
| Biotype | Characteristic Brain Patterns | Common Symptoms |
| Type 1 | Default Mode Network Dysfunction | Persistent sadness, loss of interest |
| Type 2 | Salience Network Disruption | Mood swings, irritability |
| Type 3 | Attention Circuit Abnormalities | Difficulty concentrating, memory issues |
This breakthrough shows how complex depression is and how we need a deeper understanding of its subtypes. By finding unique brain patterns for each biotype, researchers can create better treatments.
How Brain Scan for Depression Works: The MRI Technology
MRI technology is key in finding the brain patterns linked to depression. It uses advanced magnetic resonance imaging to show the brain’s activity and connections clearly.
The process starts with functional MRI (fMRI) to track brain activity. It measures blood flow changes in the brain, showing activity levels. fMRI scans are very useful because they show how different brain parts work together.
Visualizing Neural Activity and Connectivity
MRI technology is great for seeing brain activity and connections. It uses special imaging to show the brain’s networks.
Neural connectivity is about how different brain areas talk to each other. It’s important for understanding depression’s effects on the brain. By looking at this, researchers find patterns linked to depression.
Key Brain Circuits Examined in Depression Studies
Studies using MRI scans focus on important brain circuits in depression. These include the default mode network, salience network, and attention circuits, among others.
| Brain Circuit | Function | Depression Association |
| Default Mode Network | Active during rest, involved in self-referential thinking | Hyperactivity linked to rumination in depression |
| Salience Network | Switches between different brain networks | Dysfunction may contribute to emotional dysregulation |
| Attention Circuits | Controls focus and attention | Impairments associated with concentration difficulties |
By studying these circuits and their connections, researchers understand depression better. This helps in creating better diagnostic tools and treatments.

The experts’ views in the National Geographic report highlight the study’s importance. They show how this research could change how we treat depression in the future.
Depression Type 1: Default Mode Network Dysfunction
New studies in neuroimaging have found different types of depression. One key type is linked to problems in the Default Mode Network (DMN).
The Default Mode Network is active when we’re not focused on the world. It helps with thinking about ourselves, daydreaming, and remembering the past. Problems in this network are tied to depression symptoms.
Characteristic Brain Patterns
People with Depression Type 1 have unique brain connections in the DMN. MRI scans show changes in areas like the medial prefrontal cortex and the posterior cingulate cortex.
These changes make the default mode too active. This leads to too much thinking about ourselves and getting stuck in negative thoughts.
Common Symptoms and Treatment Response
Those with DMN problems often have constant negative thoughts. They find it hard to stop thinking about themselves and tend to ruminate.
How well treatments work can vary. But, research shows that therapies that aim to calm the DMN, like certain CBT or mindfulness, might help a lot.
| Symptom | Treatment Approach | Expected Outcome |
| Intrusive negative thoughts | Cognitive-behavioral therapy (CBT) | Reduced frequency of negative thoughts |
| Rumination | Mindfulness-based interventions | Improved ability to disengage from negative thinking |
| Self-referential thinking | Targeted psychotherapy | Enhanced self-awareness and reduced self-focus |
Knowing about the brain patterns of Depression Type 1 helps tailor treatments. This can lead to better results for patients.
Depression Type 2: Salience Network Disruption
New research has found six types of depression, leading to more tailored treatments. Depression Type 2 is linked to a problem in how the brain handles important information.
Characteristic Brain Patterns
Depression Type 2 shows unique brain issues in the salience network. This network is key for sorting out what’s important and what’s not. Studies have shown that people with this depression type have trouble focusing and ignoring distractions.
The salience network is vital for managing thoughts and feelings. When it’s not working right, it can cause problems with thinking and feeling. This is seen in those with Depression Type 2.
Common Symptoms and Treatment Response
People with Depression Type 2 often struggle to concentrate and manage their emotions. Recent research shows knowing the depression type can help treatment work better.
Treatment approaches for Depression Type 2 might include special therapy to improve thinking and feeling. Medications that help the brain’s activity in the salience network could also be used. This shows the need for a personalized treatment plan based on the brain type.
By understanding Depression Type 2, doctors can create better treatment plans. This can lead to better results for patients. Using advanced brain scans, like MRI, in treatment could greatly help in diagnosing and treating depression.
Depression Type 3: Attention Circuit Abnormalities
Depression Type 3 is linked to problems in how our brain handles attention. This affects how we feel and how well treatments work. Advanced brain scans can spot these issues.
Characteristic Brain Patterns
People with Depression Type 3 have brain network problems related to attention. Studies using fMRI show changes in brain connections that handle attention.
The brain shows less activity in the dorsal network and more in the ventral network. This imbalance makes it hard to focus and ignore distractions.
Common Symptoms and Treatment Response
Depression Type 3 symptoms include:
- Difficulty concentrating
- Easily distracted
- Disorganization
Treatment for Depression Type 3 might include special training programs for the brain. Some medicines can also help by improving brain connections.

Depression Type 4: Negative Mood Circuit Hyperactivity
Negative mood circuit hyperactivity is key to Depression Type 4. It needs a deep look into its brain roots. This type shows more activity in brain areas linked to bad moods. This affects how it shows up in patients and how it responds to treatment.
Characteristic Brain Patterns
People with Depression Type 4 have unique brain patterns. They show too much activity in the negative mood circuit. This is often tied to:
- More activity in the amygdala, a key emotion processor.
- Better connections between the amygdala and mood control areas.
- Changes in the prefrontal cortex, which helps manage mood.
Common Symptoms and Treatment Response
The symptoms of Depression Type 4 are very tough to deal with. They include:
- Long-lasting sadness and hopelessness.
- More irritability and anxiety.
- Trouble feeling pleasure or joy.
Treatment for Depression Type 4 often mixes medicine and talk therapy. Targeted treatments that focus on this subtype’s brain issues work well. For example, drugs that adjust the mood circuit’s activity can help a lot.
Knowing how depression works in the brain helps a lot. Spotting subtypes like Depression Type 4 lets doctors create personalized treatment plans. This makes treatment more likely to succeed.
Depression Type 5: Positive Mood Circuit Deficiency
A groundbreaking study has found a fifth type of depression. It’s linked to brain circuit problems that affect positive mood. This subtype, known as Positive Mood Circuit Deficiency, has unique brain patterns that set it apart from other depressions.
Characteristic Brain Patterns
People with this subtype have abnormalities in brain regions linked to positive mood. Functional MRI scans show changes in these circuits. This can make it hard to feel pleasure or joy.
The brain’s reward system is also affected. It shows less activity when faced with positive things. This can make it hard to find joy in things that used to be fun.
Common Symptoms and Treatment Response
Common symptoms include a persistent feeling of emptiness and a lack of interest in fun activities. It’s also hard to feel pleasure. Treatment for this subtype might include therapies that help with positive mood.
