A recent news story has started a serious public discussion about medicine side effects and family harm. The story involves a solicitor who stole £600,000 from elderly clients. Later, doctors connected his behaviour to medication used to treat Parkinson’s disease. This case shows how medicine can affect the brain in ways people do not expect. It also shows how families can suffer deeply when behaviour changes happen without warning. Many people trust prescription medicine completely. Most treatments help patients live better lives. But some medicines can change behaviour, mood, and decision-making. When that happens, the results can be tragic.
Parkinson’s disease treatment often requires long-term medication. One group of medicines, called dopamine agonists, helps control movement symptoms. These drugs increase dopamine activity in the brain. Dopamine helps control movement, motivation, and pleasure. When dopamine levels change too much, behaviour can change as well. This connection is now getting attention from doctors, researchers, and families affected by these side effects.
The BBC investigation that reported this story has opened an important conversation about patient safety. It also raises questions about whether patients receive enough warning about behavioural side effects. Understanding these risks is important for patients, families, and healthcare providers.
The Fraud Case That Shocked a Family
Frances had just arrived at work when police called her. Officers had arrested her husband Andrew, a solicitor, on suspicion of fraud. Police were searching their home. His office was sealed with crime tape. Staff were shocked. Financial records were taken away for investigation. Andrew’s legal practice handled money for elderly clients with dementia. The police soon discovered that hundreds of thousands of pounds were missing from client accounts.
Investigators later found Andrew had spent the stolen money on adult webcam websites, escorts, and antiques. The total amount taken reached £600,000. Thirteen clients were affected. Most were over 80 years old. Some were already unwell. One elderly client died shortly after the theft and her estate could not pay funeral costs. The emotional damage to victims and families was severe.
Andrew’s family could not understand what had happened. They said his behaviour seemed completely different from the person they knew. He had always been responsible and professional. The situation left the family isolated and ashamed. Friends and neighbours struggled to understand what had happened. The case soon became both a criminal matter and a medical question.
Parkinson’s Diagnosis and Treatment
Andrew had been diagnosed with Parkinson’s disease several years earlier. Parkinson’s is a brain disorder that affects movement. It often causes shaking, stiffness, and slow movement. Doctors prescribed pramipexole, a dopamine agonist medicine. The results seemed positive at first. His tremor improved quickly. He felt more energetic. He even returned to playing tennis.
Dopamine agonists work by copying the effects of dopamine in the brain. Dopamine is a chemical that controls movement and feelings of reward. Increasing dopamine activity helps reduce Parkinson’s symptoms. For many patients, these medicines are effective and safe. Doctors around the world prescribe them regularly.
However, dopamine also affects impulse control. This means medication that changes dopamine levels can affect behaviour. In some patients, this leads to compulsive actions. These actions can include gambling, shopping, and risky sexual behaviour. Many patients and families do not know about this risk before starting treatment.
Behaviour Changes Begin
Andrew’s family later noticed behaviour changes. His online spending increased. He became interested in buying antiques, including pens and pottery. These purchases became frequent and expensive. He also began spending large amounts of time and money on adult websites.
Within one year of starting medication, Andrew made hundreds of payments to webcam services. He spent more than £100,000 on one website alone. He also spent nearly £80,000 on sex workers in only four months. His phone later contained contact numbers for many escorts. At the same time, he spent £85,000 on antiques through online auctions.
These behaviours continued without his family knowing the full extent. They only learned the truth after the police investigation began. Later, a hospital doctor asked Frances whether she knew the medication could cause impulsive behaviour. She said this was the first time anyone had mentioned it.
Impulse Control Disorders and Dopamine
Doctors call these behaviour changes impulse control disorders. This condition affects a person’s ability to resist urges. It can lead to actions that harm finances, relationships, and health. Dopamine agonist drugs are known to increase this risk.
Research suggests about one in six Parkinson’s patients taking dopamine agonists may experience impulse control problems. These behaviours often appear slowly. Patients may not notice the change themselves. Family members are often the first to see warning signs.
Scientists believe the medicine overstimulates reward centres in the brain. This makes risky behaviour feel rewarding. The person may continue the behaviour even when it causes harm. This explains why people without any history of addiction can suddenly develop compulsive habits.
Legal Consequences and Family Tragedy
Andrew eventually pleaded guilty to fraud in court. The judge said the medication likely influenced his behaviour. However, the court also said he should have recognised the problem and asked for help. He was sentenced to four years in prison.
The impact on his family was devastating. His son struggled with mental health problems after the arrest. He later died by suicide. Andrew and Frances divorced during his prison sentence. After his release, Andrew lived in sheltered housing. He stopped taking the medication, but his Parkinson’s symptoms worsened. In 2020, Andrew died by suicide.
The story shows how one medical side effect can lead to legal, emotional, and financial disaster. It also shows the importance of early warning and monitoring.
A Wider Problem
The BBC investigation found many families with similar experiences. Some lost savings. Others lost homes. Many said they were not warned about behaviour risks linked to dopamine agonist drugs. In England alone, doctors issued around 1.5 million prescriptions for these medicines in one year.
Experts say impulse control disorders are underreported. Patients often feel embarrassed to discuss sexual or gambling behaviour. This makes it difficult for health agencies to track the problem accurately.
Some lawmakers are now asking drug regulators to improve warnings. They want patient leaflets to clearly explain behaviour risks and how common they may be. Regulators say side effects vary between patients and are difficult to measure precisely.
Monitoring Medication Side Effects
Doctors advise patients taking dopamine agonists to report behaviour changes quickly. Families should watch for signs such as sudden spending, gambling, or risky sexual behaviour. Early action can reduce harm. Changing medication or lowering the dose often improves symptoms.
Open communication between patients, families, and doctors is essential. Awareness helps prevent serious consequences. Education about medication risks is becoming more important as Parkinson’s treatment continues to rely on dopamine-based drugs.
Conclusion
The story of Andrew and his family shows the hidden risks of medication side effects. Dopamine agonist drugs help many Parkinson’s patients live better lives. However, they can also cause powerful behaviour changes in some people. These changes can lead to financial loss, legal trouble, and family tragedy.
Better awareness, clearer warnings, and regular monitoring may help prevent similar cases. Medicine can treat disease, but understanding side effects protects lives and families.
