THE HAGUE, Netherlands — Former Philippine president Rodrigo Duterte is suffering from severe memory loss that means he sometimes forgets his lawyer's name, according to the defense team preparing his case at the International Criminal Court.
The 81-year-old Duterte faces charges of crimes against humanity at the ICC over his so-called "war on drugs" during which thousands were killed, according to prosecutors.
His trial is scheduled to start on November 30, but judges are weighing whether he is mentally fit to be tried and ordered a medical assessment by three experts.

That assessment has not been made public but Duterte's defense and the ICC prosecutor reacted to it in documents dated September 14 but published on the ICC website on Tuesday.
Duterte "suffers from significant memory impairment that prevents him from retaining recent information and reliably accessing memories", according to the 13-page defense submission.
This makes it impossible for him to engage with the case "let alone give proper instructions to his Lead Counsel, whose name he only sometimes remembers", said his chief defense lawyer, Peter Haynes.
Haynes said he was being forced to prepare the case without meaningful input from his client.
The prosecution, in its own heavily redacted seven-page submission, concluded Duterte was "capable of meaningfully exercising his procedural and fair trial rights, and that he is fit for trial".
Under ICC rules, proceedings cannot continue if an accused is unable to understand the charges or participate meaningfully in his or her defense.
- 'Incomplete and inadequate' -
The defense also took aim at the panel of doctors, saying their report was "incomplete and inadequate" and calling for them to be cross-examined.
According to the defense submission, the experts concluded Duterte "may not have been fully applying himself" during testing, making the results difficult to interpret.
However, the experts were unable to determine whether Duterte's results stemmed from "malingering or a lack of motivation" or "a genuine inability to... complete the tests as a consequence of an underlying neurological condition", said the defense.

The defense cited some results from the examinations which they said showed Duterte thinks he is living in 2007 or 2008, that he is 84 or 85 years old, and could not recall the name of the current US president.
Haynes said in his submission that these lapses in memory make it impossible for his lawyers to prepare his defense, as they cannot rely even on what he tells them.
Such mental impairment would also affect any potential defense in the courtroom, the defense lawyer said.
"Where he cannot remember when he was last elected in the Philippines, for example, any finding that Mr Duterte could give accurate testimony in his own defense would accordingly be unreasonable," he said.
Since his arrest and transfer to The Hague, where the court is based, Duterte has been seen only once at an initial appearance via a video link.
He appeared dazed and confused, mumbling to confirm his name and seeming to doze off during proceedings.
His defense team has since applied for him to be absent on health grounds at subsequent hearings.
Presiding judge Joanna Korner has urged him to make an appearance at a pre-trial hearing on Wednesday and no defense application for an exemption has been made public.
This means Duterte could appear in person at the ICC. He would be the first former Asian head of state to do so if that happens.
Duterte faces three counts of crimes against humanity, with prosecutors alleging his involvement in at least 76 murders between 2013 and 2018 during his crackdown on drug users and sellers.
The former president's understanding of the charges against him is "at best, rudimentary," said Haynes.
