Alzheimer's disease (Criminal Minds S06E03)

TV Show
Criminal Minds Season 6 Episode 3 titled "Remembrance of Things Past"

Storyline
A family is leaving to go to a football game when the phone rings. The mother is about to answer the phone, but her husband just wants the caller to leave a message on the machine. The caller is their daughter, Jenny. She tells them she's in a lot of trouble, and by the time they listen to the message, she'll probably be dead.

Marcel Proust wrote, "Remembrance of things past is not necessarily the remembrance of things as they were."

While on vacation, Rossi is at his computer suffering from writer's block when the phone rings. He answers and Hotch describes the new case to him. When Rossi hears the killer's MO (the victims are tortured, sodomized, and then electrocuted), he quickly realizes they match an cold case that he worked on in 1993.

Rossi tells the team about an unsub called The Butcher, who was killing young blonde women in Bristol in the early 1990s. Rossi was able to pinpoint the unsub's location, but then the murders stopped and Rossi couldn't get any closer to The Butcher. The killer's MO also included the victim calling their loved ones and then ending the calls with "I enjoyed it." This didn't happen with Jenny's murder, so Rossi initially believes this might be a copycat crime.

Meanwhile, the focus switches to the unsubs. Colby awkwardly greets a blonde woman (Anna) while he's unloading a van. Later, he and his father (Lee) manage to kidnap a woman named Heather. Lee tells Heather they're going to tell her exactly what she needs to say over the phone.

Later, Lee complains that his son never helps out with anything, but Colby points out that he did help with "the woman in the hallway" when he was 10 years old. Lee wants to kidnap Anna after they're done with Heather, but Colby decides on some one else. He uses the victim, Shelly, to teach his son a lesson on how things should be done.

Rossi and Reid listen to the messages from The Butcher's other victims. Once they reach the final victim's call, they notice the message is identical to the one Jenny left, even leaving out the "I enjoyed it" line. Both victims were also found in the same place. Reid suggests there must be some connection between the two murders, but Hotch is sticking to the copycat theory. Rossi, however, still believes this is the work of The Butcher. So Hotch gives Rossi authority to investigate any leads on The Butcher, while the rest of the team focuses on the possibility of copycats.

Rossi figures out this must be the work of a father/son team, and then news comes that Heather's phone call to her father included the "I enjoyed it" line. Rossi begins to focus on the two victims who didn't leave "I enjoyed it" on their calls. The first victim didn't, and the eighth victim, Karen Bachner, didn't either. Garcia discovers that Karen Bachner had a son named Colby. Rossi remembers interviewing Karen's husband, Lee, who had told the authorities that he didn't receive a phone call, and he didn't have an answering machine so there was no message. However, there was no message because her loved ones, Lee and Colby, were already in the room.

Lee tells Colby he wants to go hunting again, and doesn't remember that he had killed Shelly. Colby wants to placate his father, so he tells him that they're going after Anna. Meanwhile, the team tracks the duo down, but they're apprehensive about arresting Lee because it appears he has Alzheimer's Disease. Lee is literally unable to remember when he killed his last victim.

Meanwhile in another location, Colby has abducted Anna and is tying her up.

Rossi shares the details of The Butcher's murders with Lee, and reminds him that he had killed his wife Karen when she found out about the previous murders. Lee gives a vital clue about a brand of electroshock therapy equipment called Lexwell. Garcia tracks down the places that still use this brand, and locates an abandoned mental hospital nearby. The team finds Colby and Anna there just in time, and Colby is reminded about the time he helped murder his mother. Colby had always believed his mother had abandoned the family. Colby suddenly remembers that his mother told him goodbye to his face, right before she was killed. As Rossi leaves Lee finally recognizes him, and tells him, "you're the reason I stopped."

Mark Twain wrote, "When I was younger, I could remember anything, whether it had happened or not. But my faculties are decaying now, and soon I shall be so that I cannot remember any but the things that never happened. It is sad to go to pieces like this, but we all have to do it."

While he is in jail, Lee Mullens attempts to take his own life by slashing his wrists, but he isn't successful.

What we learn?
We'll learn about the disease that the main killer suffered: Alzheimer's disease.


Alzheimer's disease?
Alzheimer's disease (AD)—also called Alzheimer disease, senile dementia of the Alzheimer type (SDAT), primary degenerative dementia of the Alzheimer's type (PDDAT), or Alzheimer's—is the most common form of dementia. This incurable, degenerative, and terminal disease was first described by German psychiatrist and neuropathologist Alois Alzheimer in 1906 and was named after him. Most often, it is diagnosed in people over 65 years of age, although the less-prevalent early-onset Alzheimer's can occur much earlier. In 2006, there were 26.6 million sufferers worldwide. Alzheimer's is predicted to affect 1 in 85 people globally by 2050.

Ten warning signs of Alzheimer's:
  1. Memory loss that disrupts daily life. eg. Sometimes forgetting names or appointments, but remembering them later.
  2. Challenges in planning or solving problems. eg. Making occasional errors when balancing a checkbook.
  3. Difficulty completing familiar tasks at home, at work or at leisure.
  4. Trouble understanding visual images and spatial relationships
  5. New problems with words in speaking or writing
  6. Misplacing things and losing the ability to retrace steps
  7. Decreased or poor judgement
  8. Withdrawal from work or social activities
  9. Changes in mood and personality, eg. Developing very specific ways of doing things and becoming irritable when a routine is disrupted.

Preventions
At present, there is no definitive evidence to support that any particular measure is effective in preventing AD. Global studies of measures to prevent or delay the onset of AD have often produced inconsistent results. However, epidemiological studies have proposed relationships between certain modifiable factors, such as diet, cardiovascular risk, pharmaceutical products, or intellectual activities among others, and a population's likelihood of developing AD. Only further research, including clinical trials, will reveal whether these factors can help to prevent AD.
