On February 1, 2026, a man associated with Ivaylo Kalushev received a message from him: 'Goodbye, friend, we are very tired and have no more strength.' The next day, police found the bodies of three middle-aged men at Kalushev's burnt lodge in western Bulgaria.
Dopamine is one of the most extensively studied neurotransmitters, chemicals that convey signals from cell to cell. It's the one with the highest profile outside neuroscience: often known as the 'pleasure chemical', it's depicted as the hit of reward that people get from recreational drugs or scrolling through social media. That's a gross simplification of what dopamine does; on that, researchers agree.
The movie opens with a brief prologue. A family is driving at night. They hit something on the road, which turns out to be a dog, and the dog dies. The daughter in the back seat is visibly upset. The mother consoles her by saying, "It was just an accident-Dad didn't do it on purpose." Then the title appears, and the main story begins.
Adolescence is second only to early childhood in the rapidity and sheer volume of changes occurring in brain development. Three different brain systems (and their interconnections) are at play: reward-driven behavior, harm avoidance, and regulatory behavior. At the same time, teens are experiencing powerful changes to their physical and sexual selves, accompanied by the hormonal cascade of puberty. During this period, there is an increase in brain receptors for dopamine, a neurotransmitter that has a strong effect on the experience of pleasure.
Depression is insidious. For people suffering from depression, joy is elusive. Depression is not only a general feeling of sadness or being down and out. It is a serious condition and needs attention. People suffering from depression cannot just get over it and move on. They need support, healing, and to discover the epicenter of their pain.
Anyone who is under psychiatric care, or loves someone who is, may want to read the book The Devil's Castle: Nazi Eugenics, Euthanasia, and How Psychiatry's Troubled History Reverberates Today, by Susanne Paola Antonetta. If you care about history, particularly the history of eugenics, you may be interested as well. The book may offer us more respect for the mind, for consciousness, and its diversity.
If we treat ADHD as binary (you have it or you do not), we are missing the possibility that we all lie somewhere on a continuum with diagnosed ADHD towards one end (and perhaps an ability to focus and concentrate at the other). A diagnosis of ADHD then depends on where the line is drawn. I suggest that this line has been moved in recent years, so that a large group of people have been caught up in the positive ADHD group, who would not have been previously.
Yes, there has been a shocking lack of progress in developing transformative psychiatric medicine (We need new drugs for mental ill-health, 5 February), but this may be because in mental health, drugs are not always the answer (see, for example, Richard P Bentall's Doctoring the Mind). Huge progress has been made in the effectiveness of talking therapies for example, free effective treatment for post-traumatic stress disorder (PTSD) is available to all UK army veterans through the charity PTSD Resolution.
When the Danish psychiatrist Søren Dinesen Østergaard published his ominous warning about AI's effects on mental health back in 2023, the tech giants fervently building AI chatbots didn't listen. Since that time, numerous people have lost their lives after being drawn into suicide or killed by lethal drugs after obsessive interactions with AI chatbots. More still have fallen down dangerous mental health rabbit holes brought on by intense fixations on AI models like ChatGPT.
Every day, many thousands of parents across the U.S. face the difficult question of whether to place their child or teenager on a psychotropic medication. Receiving a diagnosis of a mental disorder can be scary and confusing, for the youth as well as their parents/caretakers. What is ADHD? Depression? Anxiety? OCD? Bipolar? What are the available treatments? Do we have to use medications to treat the symptoms?
Anyone living with schizophrenia understands the true limitations of current treatment options. Antipsychotics remain the single leading treatment for the disorder, and they are riddled with undesirable side effects. Weight gain, tardive dyskinesia, and excessive drowsiness are a few. Much research is devoted to expanding the range of medication options, and few academics have pursued other avenues. However, there is a possibility that treatment for schizophrenia can be approached through cellular methods if long-term research validates early signs of hope.
Most people will forget a name, misplace their phone, or lose track of a conversation at some point. Usually, those moments pass without much thought. But for many adults, especially as they age, small lapses can trigger a much deeper fear: Is this the beginning of cognitive decline? As a neurologist, I hear this concern often. And as a researcher, I have learned something important: Worry about cognition and cognitive disease are not the same thing.
