Do I Need Medication? Therapy? or Both? Here’s What The Research Tells Us

They both work. Decades of clinical research have produced consistent and repeatable results finding that psychotherapy and medication both offer effective treatments for depression and anxiety. Neither has a decisive advantage over the other in terms of effectiveness. Head-to-head comparisons produce remarkably similar results.

The best evidence for this was a large scale analysis that looked at 153 randomized trials involving over 30,000 participants. They found that psychotherapy alone, and psychopharmacology alone led to meaningful reductions in depression symptoms without any significant difference between the two.

This is notable, because if you had to pick one option only, either would work.

The Math is Where Things Get Interesting:

• Medication alone: 50-55% response rate
• Therapy alone: 50-55% response rate

When you combine the two (Medication + Therapy), the response rate is 65-75%.

This is really important because it means that despite having similar response rates, the two interventions lead to improvement in different ways. The fact that the combination out-performs both single therapies is the true key finding of all this research. It increases the likelihood of responding by almost 50%.

This type of interaction is called a synergistic effect. The combination of the two leads to enhanced benefit grater than the individual parts. The reason why this happens comes down to how psychotherapy and medications work on the brain.

The Neuroscience Explained:

The brain communicates through connections called neurons. Neurons are connected end-to-end through junctions called synapses. You can’t form new roads, but you can improve the synapses and make them stronger. When someone is depressed or anxious, the function of these connections is disrupted. Stress can lead to changes that weaken the synapses reducing the efficiency of the nerve pathways.

Medication addresses this at a chemical level. The thought is that by increasing the availability of. neurotransmitters (serotonin, dopamine, norepinephrine) in the synapse, you can strengthen the synapse over time through adaptation. These medications trigger the growth of new connections, and that growth can be permanent.

Therapy works through a complimentary mechanism that relies on the underlying principle (use it or lose it). Each time you practice a new pattern or thinking, you activate the appropriate nerve pathway and reinforce it. Doing this consistently over time achieves the same goal – synapse growth.

When you combine the two, you get both benefits. You have the chemical process optimizing synapse growth at the biological level, and you have the psychotherapy reinforcing the correct nerve pathways. The medication makes the therapy work better, and the therapy can make the medication changes permanent. One without the other leaves half of this problem unaddressed.

Does That Mean Everyone Should Get Both?

Not-necessarily. The right treatment depends on a variety of factors and both options have risks and benefits. In general, the combination of both the best path to improvement. However, lifestyle and patient preference heavily impacts this.

With medication – there is no free lunch. They cause side effects and that risk is real. Many people tolerate the medications well, and side effects are so minimal they go unnoticed. Other times, the side effects lead to changes in other areas of their life that create friction.

Therapy is a big time commitment. If a patient has a heavy workload and isn’t able to attend regular sessions – therapy isn’t as helpful. Cost can also be a concern for therapy.

There are some conditions where traditional therapy offers no benefit. Some of these require medications for improvement.

For mild symptoms – a 55% response rate is decent. Avoiding side effects, or taking a medication and foregoing therapy might be the right choice for that person given the lower stakes. It all comes down to risk/benefit type thinking and understanding this balance.
